When a WebGL canvas is larger than the maximum renderbuffer size, we downsize the renderbuffer until it fits within that maximum. It should be stretched to the original canvas size when it's displayed, but instead we get the downsized size.
Testcase attached.
Does this still reproduce?

Yes, it does. Attached is a severely bitrotted patch I was working on, until I discovered that cairo doesn't like scaling by more than INT16_MAX(-ish), outputting nothing instead in the attached test case.
I figured it's better to fail and show something tiny than not show anything at all, but maybe not?
