 ### Bug Fixes
 
+-   Prevent no-op synced entity updates from marking records as dirty and triggering unsaved-changes warnings.
 -   Footnotes: Treat unreadable `footnotes` post meta as no footnotes instead of throwing. Malformed JSON, or valid JSON that is not an array, threw inside a store subscriber where no error boundary catches it, so the edit was dropped and the post silently stopped saving ([#81201](https://github.com/WordPress/gutenberg/pull/81201)).
 -   Ensure revision resolvers finish after fetched revisions are stored.
