From 970810d115305ace8f66f6be140f2d6d80ef8462 Mon Sep 17 00:00:00 2001 From: Erica-cod <2779428708@qq.com> Date: Thu, 16 Apr 2026 00:02:59 +0800 Subject: [PATCH 1/3] fix: arrow key navigation causes white blank area (#5105) dynamicSetX/dynamicSetY returned early when screenLeft/screenTop was null, leaving body group position stale. setBodyAndColHeaderX/setBodyAndRowHeaderY could incorrectly read border element as lastChild.
