## Summary by CodeRabbit

- Bug Fixes
- Reduced repeated mobile editing notifications; the notice now appears
once and only reappears after you dismiss it.
- More consistent notification behavior on mobile for a less disruptive
editing experience.

- Refactor
- Streamlined internal event handling to improve reliability and reduce
potential listener leaks, resulting in smoother interactions.
