+Subject: [PATCH] x11/ozone: fix two edge cases
+
+WindowTreeHost::OnHostMovedInPixels() may trigger a nested message
+loop (tab dragging), which when the stack unravels means this may
+be deleted. This adds an early out if this happens.
+
+X11WholeScreenMoveLoop has a similar issue, in so far as notifying
+the delegate may delete this.
+

+TEST=WindowTreeHostPlatform.DeleteHostFromOnHostMovedInPixels
