Fixed issue in details view, that "sometimes" the rubberband selection only selects one item after an item has been deleted.

It took me nearly 30 minutes to find out how to reproduce this issue 100 % reliable:
- a confirm dialog must be shown (thanks a lot to Dario for the hint!)
- the most important part: the keys (e. g. Shift + Del) must be pressed long enough until the confirm dialog grabs the focus from the details view...
