I'm not sure why it's being run in this weird job. It should only be being run in mochitest-webgl2-core jobs.
Ok, so this looks like it gathers all tests that are conditional, and then runs them? I see it's deciding to run webgl2-core for some reason, and it really shouldn't be. Who is the owner of the TVg jobs?

TVg is part of "test verification", documented at https://developer.mozilla.org/en-US/docs/Mozilla/QA/Test_Verification. tl;dr: TVg tried to run this test because it was modified; it won't run this test otherwise, so no failures are expected on future pushes (unless/until the test is modified again). TVg runs as tier 3 -- it should not be cause for backout, and you should feel free to wontfix it. But, a TVg failure may indicate a weakness in the test. In this case, it looks like test_2_conformance2__rendering__line-rendering-quality.html failed on the first run of the test -- as though the test is relying on browser state set up by an earlier test?

That test fails on some of our try configurations. (graphics testing is a pain) We usually mark such failures, but this test should never run on this configuration of hardware, so it wasn't marked properly. Specifically, we haven't gotten webgl2-core stood up on linux yet, so we never run that job on linux, so we shouldn't ever see these sort of failures. :)
