Subject: [PATCH] Fix initial window focus bug

Summary:
When launching flipper release build, the initial window focus was wrong, so it appeared unfocussed.
Clicking away and then back to the window would fix it.

This should set the initial focus to be correct from the start.

Task has more details.
