Builder Linux FYI Release AMD failure: WebglConformance_conformance_rendering_draw_webgl_to_canvas_2d_repeatedly

Builder Linux FYI Release AMD failure: 

https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Linux%20FYI%20Release%20%28AMD%20R7%20240%29/2255

pretty clear that there's some kind of swizzle error happening here:

kbr@: The failing test was first added to the WebGL conformance set in da239df8decc27d4b61f49efe51906a585b22b5b so maybe you could take a look? 

(A test suppression is in the queue.)

Thanks for finding this Robert. The failure mode of this test indicates some sort of driver bug. Unfortunately this AMD GPU and associated driver are pretty badly obsolete, and not receiving new updates. It's difficult to find a newer single-slot card that will fit into the 1U servers in the data center, and the labs team is evaluating new housings which can accommodate current consumer grade cards.

Unfortunately I'll have to close this as WontFix. It would be great to un-suppress this in the future if we get newer AMD cards in our Linux workstations.
