Apparently sending tab key via UIController doesn't move the focus forward on iOS. There are tests with form controls where it seems to be working so it's rather mysterious. It probably needs to be investigated in another bug as there are other tests that are currently skipped on iOS for similar reasons.
Hm... I can't reproduce the test failure of imported/w3c/web-platform-tests/mathml/relations/html5-tree/tabindex-002.html on macOS Mojave. Maybe it's high Sierra only?? That's weird though...
This is so frustrating. I've been trying to land this patch for the last three days :(
