+From 5e3a738b1204941aab9f15c0eb3d06e20fefd96e Mon Sep 17 00:00:00 2001
+From: Scott Violet <sky@chromium.org>
+Date: Mon, 8 Mar 2021 21:07:39 +0000
+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.
+
+BUG=1185482
+TEST=WindowTreeHostPlatform.DeleteHostFromOnHostMovedInPixels
