Pressing "enter" really quickly after entering a password on login page or a search string
When entering a password on the login page or a textstring in the search field and then pressing "enter" really quickly, some characters were cut off. This lead to undisired actions - the wrong password was entered or the search result was not as expected.
Frozen popups
Noticeable mostly on the search overview when hovering over the names of people and item lists. When using laptops with browsers which use touch mode, the popups froze and could not be closed unless the page was refreshed.
