Bug 205664 – webgl/2.0.0/conformance2/renderbuffers/multisample-with-full-sample-counts.html is failing

• Component: WebGL
• Status: RESOLVED CONFIGURATION CHANGED

[Alexey Proskuryakov]

webgl/2.0.0/conformance2/renderbuffers/multisample-with-full-sample-counts.html was marked as passing when we switched to ANGLE, but it's actually still failing on hardware/software configurations where it used to fail.

The failure reproduces on Catalina WK2, Mac mini 8,1, but not on iMac Pro.
