Investigating... This seems to be a case from different selector parsing.
Attached file simplified testcase (deleted) —
The website is using a specific selector to do browser-sniff. This case it is the -moz-tree-row pseudo-class, which is part of thing tracked in bug 1348488.
Depends on: 1348488
This is problematic, though, because :-moz-tree-row is a non-standard internal selector. I believe we want to unship it from being accessed from web content at some point. It is probably worth understanding why this website needs this trick.
Another approach ahead is to unship :-moz-tree pseudos from web content, so that this website becomes broken in Firefox without Gecko (and thus not a regression from stylo). That can be done via bug 1379031.

That can be done via bug 1379031. I meant... without Stylo...
