TYPO3 Core

In the Backend User Listing.
When adding/removing users to the compare selection, the UI reacts weird.

See attached screenshot.

I have assumed, when I add a user to the list, the "compare" button changes from a plus to a minus sign so that I can remove this user from the compare list by clicking either the minus button at the top, or by clicking the "compare" button again.

I added three users to the compare list but the "compare" buttons in the list view are inconsistent:

- "Addy" is in the compare list, but her button shows a plus (clicking it does not change the list).
- "admin" is in the compare list and the button is correct (and I can remove this user again).
- "Alvin" has the same issue as "Addy" (his button should show a minus as he's in the list).
- "Roberta" is NOT in the list, but her button shows a minus (clicking it does not change the list).

...or maybe I misunderstand the UI concept behind this page? :-)
