I see neither dri3_get_buffer_age nor any wr_ calls in that crash stack. What's connecting that crash to this bug?

I should've elaborated how this crash was created. It comes from https://bugzilla.mozilla.org/show_bug.cgi?id=1714779#c19 and is the result of the user using kill -ABRT to generate a crash report for a hung browser.

With the crash report for the hung browser I expanded all threads and looked at the "Renderer" thread to blame dri3_get_buffer_age

DRI stuff, anything that looks familiar?

It prints 'We couldn't find the crash report for the Crash ID you requested' so it's perhaps already deleted.
