Hello Wes,
This failures seems to have started with your patch as seen here: https://treeherder.mozilla.org/#/jobs?repo=autoland&resultStatus=success%2Ctestfailed%2Cbusted%2Cexception&searchStr=android%2C7.0%2Cx86-64%2Cdebug%2Cweb%2Cplatform%2Ctests%2Ctest-android-em-7.0-x86_64%2Fdebug-web-platform-tests-reftests-e10s-5%2Cw%28wr5%29&revision=253fa3bd2d74f4f0aa694f84ccfec2d2a93849b7&selectedJob=252510221

Pretty sure this just needs a metadata update.

Yeah, this seems to be a test that fails in Android, and I think that's a bug in the test assumptions. I think it has to do with the fact that scrollbars on Android take up no space, and that baseline-alignment is different between scrollable flex (in the testcase) vs. scrollable block (in the reference case).

I'll spin off a separate bug to look into this in more detail and fix the test if needed.

Backed out for perma fails on testrunner.py.
