:gw, is there any chance this was caused by one of your changes in Bug 1572197?

Yes, the plane-split dependency update in that patch was to fix a Windows-only failure in perspective-scrolling-1.html (the same test), so it does seem that it's also fixed it on that Android platform.

What is the right course of action here - should I land a new patch with updated expectations, or is that something you would do, or is there something else that needs to happen here?

Landing a patch would be the appropriate thing to do in this case. It's not worth backing it out since it doesn't appear to affect tier-1 jobs.
Whenever you have a bit of time to do so, would be great. Thank you for helping out!

Attachment: Bug 1572779 - Update test expectations for perspective-scrolling-1.html.

This bug became an unexpected PASS on tier-2 android platform after
landing the fixes for bug 1572197. The fixes in that bug were
specifically to fix this test on windows platforms, so it's not
surprising that it also fixes it on android.
