	   that is almost immediately closed again. This makes Cage
	   think there are no views left, which results in it
	   exiting. However, after this initial (unmapped) surface,
	   the "real" application surface is opened. This leads to
	   these applications' startup sequences being interrupted by
	   Cage exiting. Hence, to work around this issue, Cage checks
	   whether an XWayland surface has ever been mapped and exits
	   only if 1) the XWayland surface has ever been mapped and 2)
	   this was the last surface Cage manages. */
