            Errhemmm... Fuck! This! Shit!
            Not only is Qt5 too dumb to set the window title by parameter, if one
            does it, at least on X11 Qt5 doesn't set the property on the platform
            window *before* mapping it, but *while* - causing an IPC race condition
            with the WMs that will pick up the "old" title, but also miss the property
            update because it can happen while they're configuring the window.
            Awesome.
            Because we can't retroactively preceed the mapping, we at least need to
            make sure that the title gets updated after the window is mapped and
            configured - what we can only guess witha timer... *grrrrr*
            Since setting the same title is idempotent and skipped in ::setWindowTitle
            (what would be great if the entire thing wasn't broken to begin with)
            We need two steps to first clear and second reset the title - maximzing
            the server roundtrips...
            But hey, abstract and wayland and QML... FUCK! THIS! SHIT! *grrrrrrrr*
