Clicking anywhere but "Confirm" dismisses logout prompt

[XV-02]

When attempting to logout, the logout prompt is dismissed if anywhere other than the confirm button is clicked. This seems to stop the logout process, but the behaviour is non-obvious in the case of a mis-click, especially when the mis-click is executed while trying to hit "Confirm".

The correct behaviour should probably be for the prompt to persist unless one of the two buttons is successfully pressed.
