Password boxes cleared while logging in #15
Description
If you press backspace while the app is trying to connect in the login screen and the username/password boxes are disabled, the password box will be cleared.
This bug appeared after fixing the problem of being able to navigate with backspace. I think it might be connected with this, as a passwordbox will be cleared upon navigation (trait of the PasswordBox), so I think that before the fix in commit ed10108 cancelles the event, the PasswordBox receives the event, uses it to clear the passwordbox but then the navigation itself is stopped.
This is just my speculations, might also be something entirely different.
