Regression Notes

1. Potential unintended areas of impact Most anything in the editor view.
2. What I did to test those areas of impact (or what existing automated tests I relied on) Manual testing outlined in https://github.com/WordPress/gutenberg/pull/58475.
3. What automated tests I added (or what prevented me from doing so) None, this does not add new functionality.
