Summary

Two independent, both live-verified fixes for the mobile Reports page (/reports):

  • Touch-hold jitter on reorderable sections. reports_sortable_controller.js used a 150ms hold delay with no move-cancel threshold, so a normal scroll gesture (pause then move) could activate drag mode mid-scroll, visibly shifting the section and fighting native scroll. Ports the dashboard's already-merged fix (800ms hold delay, 10px move-cancel threshold, native-dragstart guard during touch, touchcancel wiring, text-selection suppression during hold) and aligns the grip handle's visibility with the dashboard's (desktop-only, hover-revealed).

  • Full-page scroll freeze on iOS Safari, fixes Bug: Reports page completely unscrollable on iOS Safari (iPhone/iPad) since v0.7.4-alpha.6 #3093. The clickable category-row link added in Make report income/expense categories clickable #2923 used a position: relative <tr> with a position: absolute; inset: 0 stretched ::before link, repeated across every row in up to four <table>s per page load. position on table-internal elements is unreliable across browsers, and on WebKit/iOS Safari it corrupted the ancestor scroll container's computed scrollHeight badly enough to freeze scrolling for the entire page — reproducible even with JavaScript fully disabled, confirming it was a pure CSS/table-layout issue, not a touch-handler bug. Replaces the stretched-link overlay with a normal-flow <a class="flex items-center gap-2"> wrapping the icon, name, and entry count — same click target and hover behavior, no positioning inside the table. Confirmed fixed live on a real iPhone.

Test plan

  • bin/rails test test/controllers/reports_controller_test.rb — 34/34 passing (run inside a from-main container build, no local Ruby available)
  • Live-tested on a real iPhone (Safari): Reports page scrolls normally again, no more full-page freeze
  • Live-tested touch-hold jitter fix: natural scroll gestures no longer trigger drag mode; a deliberate 800ms+ press-and-hold still activates drag-to-reorder correctly
  • Verified clickable category rows still navigate to /transactions filtered by category on a quick tap; non-clickable rows (e.g. Other Investments) remain non-interactive
  • Verified collapse/expand and mouse drag-and-drop (desktop) still work unaffected

Summary by CodeRabbit

  • Bug Fixes

    • Improved touch-based report section reordering with a longer hold before dragging.
    • Prevented accidental drags from minor touch movement and added cancellation handling.
    • Preserved text selection outside active drag interactions.
    • Made category rows, amounts, and percentages consistently clickable when transactions are available.
  • UI Improvements

    • Refined reorder controls for large-screen layouts with clearer sizing, alignment, and grab cursor styling.

…croll

Port the dashboard's proven touch-drag pattern to reports_sortable_controller:
raise the hold delay to 800ms, add a 10px move-cancel threshold, guard native
dragstart during an active touch sequence, wire touchcancel, and suppress
text selection while a hold is pending. Previously a 150ms delay with no
move-cancel threshold meant a normal scroll gesture (a brief pause then move)
could activate drag mode mid-scroll, visibly shifting the section and
fighting native scroll. Also aligns the grip handle's visibility classes
with the dashboard's (desktop-only, hover-revealed).

…S Safari

Fixes we-promise#3093. The clickable category-row link (we-promise#2923) used a `position:
relative` <tr> with a `position: absolute; inset: 0` stretched ::before
link, repeated across every row in up to four <table>s per page load.
`position` on table-internal elements is unreliable across browsers, and
on WebKit/iOS Safari it corrupted the ancestor scroll container's computed
scrollHeight badly enough to freeze scrolling for the entire page, not just
the affected rows — reproducible even with JavaScript disabled, confirming
it was a pure CSS/table-layout issue rather than a touch-handler bug.

Replace the stretched-link overlay with a normal-flow <a class="flex
items-center gap-2"> wrapping the icon, name, and entry count — same click
target and hover behavior, no positioning inside the table. Non-clickable
rows (e.g. Other Investments, trade-only buckets) are unaffected.

Update the two clickable-row tests: the link's accessible text now also
includes the icon and entry count, so exact-text assertions become regex
matches; add a negative assertion that the stretched-link classes are gone.

📝 Walkthrough

Walkthrough

Report touch dragging now uses delayed activation, movement cancellation, native-drag suppression, and touch cancellation. Category rows now use normal-flow links or non-clickable flex containers. Related view styling and controller tests were updated.

Changes

Touch drag interactions

Layer / File(s) Summary
Touch drag lifecycle and controls
app/javascript/controllers/reports_sortable_controller.js, app/views/reports/index.html.erb
Touch activation uses an 800 ms hold. Movement beyond a 10 px radius cancels pending activation. Active drags use current touch coordinates. The controller handles touchcancel, restores text selection, and suppresses native dragging. The view wires touchcancel and updates drag-handle styling.

Category row links

Layer / File(s) Summary
Category row rendering and assertions
app/views/reports/_category_row.html.erb, test/controllers/reports_controller_test.rb
Category rows render shared content in normal-flow links or flex containers. Tests match localized names and verify that stretched-link classes are absent.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to f14fa

This PR changes Reports-page touch reordering and category-row navigation, but a canceled touch can still save an unintended section reorder, and the category icon hover affordance is inconsistent across row links. The cancellation behavior should be corrected or explicitly accepted before merging.

Comment thread app/views/reports/index.html.erb Outdated
touchcancel routed to touchEnd, which moved the section to the last
observed position and called saveOrder(). A canceled touch gesture
(e.g. an interrupting system gesture) should discard the pending
reorder instead of persisting it.

Addressed the one substantive finding raised independently by both Codex and CodeRabbit: touchcancel was wired to touchEnd, so a canceled touch gesture (e.g. an interrupting system gesture mid-drag) would move the section to its last observed position and persist the reorder via saveOrder().

Fixed in b8ba3c1touchcancel now routes to a new touchCancel() action that clears drag styling/placeholders and resets touch state, without moving anything or saving. Both review threads resolved.

Reviewed the touch-jitter/scroll-freeze fixes. The Stimulus touch-hold logic (800ms delay, 10px move-cancel threshold, touchcancel handling, native-dragstart guard) is sound and correctly resets state on all exit paths. One genuine regression found in the category-row link refactor — left as an inline comment.

Wrap the amount and percentage cell content in their own normal-flow
<a> tags to the same href, so the click target matches the pre-we-promise#3132
full-row behavior without reintroducing the position:absolute
stretched-link trick that broke iOS Safari scrolling.

Keep the hover state on the full clickable row.

group/category-row is attached only to the first-cell <a>. Hovering the amount or percentage links therefore does not activate group-hover/category-row:scale-105 on the category icon. Move the named group class to the <tr> and remove it from the first link, or apply the same hover state to all three links.

Daily PR scan review for head f14fa9c1246af82fa9385854c4d5cbaef9ff9176.

Ready for merge from this scan. Current evidence: Pull Request workflow run 32626829972 succeeded, Pipelock Security Scan workflow run 32626829880 succeeded, and the combined status reports CodeRabbit success. The earlier touch-cancel and shrunken-click-target findings were addressed by the current diff: touchcancel now routes to reports-sortable#touchCancel, and _category_row.html.erb wraps the amount and percentage cells in links to the same transactions_href.

@jjmata follow-up work: no separate follow-up issue looks important enough from this diff beyond watching real-device Reports behavior after merge.
