Description:
These tests are flaky timing out on Mac wk1 Debug. They have both been flaky timing out for most of the visible history, with webgl/2.0.0/conformance2/state/gl-object-get-calls.html flaky timing out for nearly all of the visible history.

Yes, these tests always take close to 30 seconds in debug, sometimes slightly more or less.
