When you hit the close button on the window, it hides in the system
tray, or when you hit File>Hide or Ctrl+H while the application has
focus. I have some testing code in to see why the icon isn't being set,
but still can't figure it out. The icon is definitely loading, it's
just when I set it to the icon it's no visible. I'm even not getting
console output saying no icon is being set.
