window state reverting to maximized during unmaximization.  This
had two causes: the first was that the window geometry would be
set even before ack_configure, which was fixed by moving setting
the window geometry into NoteBounds, and the second was that
NoteBounds would sometimes resize the window back to its old
dimensions if a commit (or subsurface update) happened between
SetBoundsSize and the configure event arriving, also confusing
the window manager.
