No -- the window manager is doing what it has been told to do, the
problem is with what the ICCCM says about how to handle such cases.

I should point out I have no idea if the issue reported is what I have
outlined or not, I'm simply guessing.

A window can be mapped and in the WithDrawn state (i.e., not
displayed) on screen.  The long and short of what I've detailed there
is that should a MapRequest is followed by a synthetic (fake)
UnmapNotify request it should simply ignore the MapRequest, since it
will map it properly when the real MapRequest is issued.
