It looks like I marked it NeedsRebaseline for Win10 only because it was marked as failing on Debug on everything else already, because you're not allowed to only rebaseline Release. And lo, it passes on Win10. So I'll try a rebaseline on all platforms and see what happens.

Hold on it looks like there's activity in the other bug, so I'll merge this in there before I start messing with stuff.
