Joel, would skip-if(winWidget&&AddressSanitizer) work to disable this test on windows asan?

By the looks of the reftest-analyzer the whole image is missing. https://hg.mozilla.org/mozilla-central/raw-file/tip/layout/tools/reftest/reftest-analyzer.xhtml#logurl=https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/HeIcTufUT0uKoKb7kzyN0w/runs/0/artifacts/public/logs/live_backing.log&only_show_unexpected=1

Thanks for pointing it out. I would like this backed out from beta as well. Nightly has a proper fix.

These patches don't graft cleanly to the 137 beta branch.
If the fix is the one in bug 1952863, it grafts cleanly to beta.

Comment 38

[Nicolas Silva [:nical]]

Thanks Pascal. I submitted a new version of the backout that applies cleanly on beta 137. Thankfully the conflict was only on a white space change so it should still be less risky than uplifting the nightly fix.
