Please just skip any "youtube-plugin-replacement" tests. This is dead code.
Also bug 223750 and bug 229505 cover the same assertion. No need to file new ones.
I just noticed that this assertion is a duplicate of the bugs that you mentioned. Will mark the expectations. Thanks!
Updated expectations to skip the test on all platforms in bug 229505
