Fix #39172. Send the synthetic configure notify event _after_ reparenting

into WindowWrapper (in WindowWrapper::show() triggered by Client::show()).
Some toolkits go up the window hiearchy when finding the "real" position
of the window (i.e. the topleft decoration border corner), and if they
receive the ReparentNotify after the synthetic ConfigureNotify, they'll
miscalculate it. (Hmm, I wonder how Qt does it since it gets it right.)
