Hi Nathan, can you please take a look at this? It may be regressed by 1748585.

Comment 1

[Nathan LaPré]

Yup, I'm taking a look at this. It looks like I didn't see the problem in testing Nightly since it's triggered by the browser.opaqueResponseBlocking.syntheticBrowsingContext pref being set to false - it's true by default on Nightly. When the pref is false, we take a different path when testing an embedded image, which causes the failure. I don't understand exactly how my change might have broken this yet, but it seems related so I'm continuing to investigate.

This failure did not occur in today's beta-sim: https://treeherder.mozilla.org/jobs?repo=try&group_state=expanded&revision=34adafe31e0c69351f484bfd94787fb4c0489f35

Comment 5

[Nathan LaPré]

Yup, since the patch addressing this alt="" bug got backed out for causing this issue (among others), this bug should be fixed. When I re-submit an updated patch for that linked alt="" bug, I'll be sure to preemptively address this issue so the bug doesn't resurface.

Comment 6

[Cosmin Sabou [:CosminS]]

This was fixed by backing out Bug 1748585 from Firefox 108 as the above comment states.
