Issue Summary

'local-id'tag injection causes false formatting diffs in "View Changes" modal without content modification

Steps to Reproduce

1. Create a new page with a text paragraph.
2. Manually scrub (remove) the 'local-id' tag/attribute from the page's storage format (to simulate a page state before the tag injection).
3. Enter "Edit mode" again without making any changes to the content.
4. Click the "View Changes" option (in the more actions menu '...').

Expected Results

The "View Changes" modal should indicate that there are no changes, or show an empty diff, as no content was modified by the user.

Actual Results

The paragraph is displayed in the "View Changes" modal as if it has been modified. (Note: This appears to be triggered by the automatic insertion of the local-id tag upon entering the new editor infrastructure. Unlike CONFCLOUD-56893, the diff is not empty; it explicitly shows the content as changed.)

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available.
