Windows keyboard focus-stealing is actually a bit bugged (I can't
remember the issue number off the top of my head). There are a number of
media embeds and such that cause it to steal keyboard focus from the
rest of the UI until the the browser window is closed (even if the
browser window is not uppermost). This is fairly easy to demonstrate
with web-profiles.
