…tency Summary: Changelog: [General][Changed] - Refactor how shadow tree revisions are promoted as latest for JS consistency Changes `LazyShadowTreeRevisionConsistencyManager::updateCurrentRevision` to pull the latest commited revision for a given surface id instead of accepting the new revision as a parameter. This way, the new revision is read from the same place for every update, which opens up the way to implement commit branching. This change will allow to always read from the JS tree revision, if it exists. Differential Revision: D88151490
