  • If you have a window and a tool that is not the min or max say [?] 'help' or something like that. If I click it two fast it treats it as a dbl click for what I assume is the title dblclick to expand the window fullscreen.

Test Case:
Setup a window with a custom tool say ">>" or "?" icons and do not put a handler then click it quickly and it should go fullscreen.
