Comment 2 Simon Fraser (smfr) 2021-08-31 11:08:07 PDT

Please just skip any "youtube-plugin-replacement" tests. This is dead code.

Comment 3 Simon Fraser (smfr) 2021-08-31 11:09:07 PDT

Also bug 223750 and bug 229505 cover the same assertion. No need to file new ones.

Comment 4 ayumi_kojima 2021-08-31 11:14:35 PDT

I just noticed that this assertion is a duplicate of the bugs that you mentioned. Will mark the expectations. Thanks!

Comment 5 ayumi_kojima 2021-08-31 11:36:12 PDT

Updated expectations to skip the test on all platforms in bug 229505
