- 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.
- Improved node resizer positioning to be more accurate
- Fixed drop handling not running within editor margin space
- Made media dom update smarter to reduce reloads
- Fixed media alignment, broken due to added wrapper
