- hold on to a reference an editable element's editor for too long,
- preventing it from being destructed.
-
- However, when an editor's owning node is being destroyed, the editor
- sends out a DocumentWillBeDestroyed notification. We can use this to
- clean up our references to the object, to allow it to be destroyed in a
- timely fashion.
