Screenshot depicting the problem in question.

1. Open an editor.
2. Drag it to the same stack with the 'Package Explorer'.
3. Activate that editor.
4. Resize the stack so that only the editor's tab can be seen (and the tab of the 'Package Explorer' is obscured behind).
5. Now drag the editor back to the shared area. This may take a few tries.
6. An AIOOBE is thrown. The editor is now also taking up a fraction of the spaceb in the shared area (see attached). New editors that are opened do not seem to have this problem though.
