This test fails for both "xorigin" mode enabled and "xorigin && fission" mode enabled.

Component: DOM: Content Processes → DOM: Core & HTML

It looks like the problem here is just that when the test document is cross-origin from its parent, it winds up with the windows-1252 encoding, rather than the UTF-8 origin it winds up with when they're same-origin. Adding <meta charset="UTF-8"> to the <head> fixes it.
