QWidgetWindow: Stabilize test on Xcb
Showing, hiding, and showing a window can result in the Xcb QPA plugin
warning about
qt.qpa.xcb: internal error: void QXcbWindow::setNetWmStateOnUnmappedWindow()
called on mapped window
The point of the test is to verify that we get a paint event on a window
that is shown again after having been hidden, not to verify that async
windowing systems can handle a show/hide/show sequence. So wait for the
window being exposed before we hide it.
