Sporadical WebGL test failures on Monterey x86_64 bots

Investigate why

From bug 254690
> This problem doesn't seem to be iOS specific. Some WebGL tests are flaky these days for some ports.

Seems like 1.0.x tests time out in sporadic way, 2.0.y tests do not?

Comment 3 Kimmo Kinnunen 2023-04-11 05:59:51 PDT

Note: disregard 2.0.0 / 1.0.3 differences. 2.0.0 tests are run with wrong parameters, they're equal to 1.0.3 tests for the most part.
