Clicked tabs and buttons remain focused after cancelled confirmation dialog

[Egor Stambakio]

How to reproduce: go to Edit page, change somehing, click on any tab other than the current one. Confirmation dialog pops up. Click Cancel. The tab you clicked remains grey. The same applies to Delete buttons on Search view, or any other button which requires confirmation.

Expected behavior: if action is cancelled, button (or tab) loses active/focused state.
