10960	[IE10+] Error thrown and broken range produced while creating bookmarks	Olek Nowodziński		"This ticket refers to the [https://github.com/ckeditor/ckeditor-dev/blob/ecf76bf/plugins/tabletools/plugin.js#L406-L411 dirty fix] we ""developed"" for #10308. 

----

The problem re-appeared while testing 4.2.2 in `dt/plugins/tabletools/tabletools.html` (full-all) because of undo manager creating snapshots.

Those lines in tabletools are not an actual fix because they don't touch the root of the problem, but rather some aspect we merely identified.

Even though the solution is sufficient for 4.2.2, we got to:
* Check whether IE11 is also affected.
* Find the real source of that problem.
* Provide a real fix."	Bug	closed	Normal		Core : Selection	4.2.2	wontfix
