Good investigation Kimmo!

Even if the code path that makes Chrome's validating command decoder work for this game isn't covered under one of the driver bug workarounds, I think it's still likely that working around the remaining driver bugs that affect WebGL 2.0 conformance will also fix this game. Maybe some of the needed workarounds were hard-coded.

James has triaged these failures in the WebGL 2.0 Implementation Logistics spreadsheet (just shared with you). If we find a couple of the most likely candidate driver bugs and try implementing workarounds in ANGLE, this game might start working.

I have a feeling this might still be related to either needing to reset the texture's base level in some situations (Chromium's reset_base_mipmap_level_before_texstorage and reset_teximage2d_base_level workarounds) or IOSurface- and CopyTexImage2D-related issues (use_intermediary_for_copy_texture_image - though that might have been fixed in newer OS releases).
