Lexical: Fixed media resize handling

- Updating height/width setting to clear any inline CSS width/height
  rules which would override and prevent resizes showing. This was
  common when switching media from old editor.
  Added test to cover.
- Updated resizer to track node so that it is retained & displayed
  across node DOM changes, which was previously causing the
  resizer/focus to disappear.
