Steps to reproduce:
- Limit access to problems by using tags for a user group (Administration > User group > Tag filter)
- Save changes
- Try to roll back the change (i.e. remove all the tag filters)
You should click "Remove" N times (one time per each host group). What if you have 100 (or 1000) groups in the list
It would be great to be able to select all (or some of them) in this situation.
