List View sorting by category is done by category id instead of titles
This is the scenario:
There are entries assigned to categories, and "Categories" is made visible for multi editing purposes.
Clicking on the "Categories" header, the entries should now be ordered alphabetically by category title.
This is not the case, the result is chaotic.
As the screenshot shows, the categories are ordered in no specific order, not even some kind of consistency is deductable.
