Code review comment for lp:~dandrader/unity8/childWindowFocus

Ok, but I just found a bigger issue though:

1. Launch kate
2. Press Ctrl+O or click the Open... toolbar button
3. Press Esc to close the file dialog
(4. The focus is gone but that's a separate issue indeed)
5. Manually activate the main kate window (e.g. click decoration)
6. Notice you can't _anything_ type anymore in the kate window
7. Press "O" alone, notice the file dialog gets opened again

Seems like the Ctrl key gets stuck somewhere
