--- Comment #6 from Mark Janes <mark.a.janes at intel.com> ---
Because this commit enables an extension, it is not clear that this bug
identifies a regression in Mesa.   It may be that it enable an execution path
that is buggy (in Chrome or in Mesa)

Denis: can you see if the same tests fail on the specified commit in Firefox?

Full set of tests that fail as described:
