From d13d0924c4e18ecc4b79adf0fec142ee9a9eaa14 Mon Sep 17 00:00:00 2001
From: "liberato@chromium.org" <liberato@chromium.org>
Date: Mon, 7 Mar 2022 20:17:13 +0000
Subject: [Backport] CVE-2022-0971
Don't use a deleted RenderFrameHost.
Since we do not check for frame liveness, a RenderFrameHost might be
deleted (in the use-after-free sense) without another call to
RenderFrameDeleted. So, WeakPtr it to avoid these cases.
Bug: 1299422
Task-number: QTBUG-101946
Change-Id: Ie4fe85f88ef80f4e4c3d0452397c0e5050ed881c
