Comment on attachment 90090 [details] Patch How was the logic error discovered? Would it be possible to add a WebGL layout test to cover this case?

Some of the webgl layout tests started crashing due to this bug, after an unrelated change to BitmapImageSingleFrameSkia caused the problem to become visible. I can't really think of a type of test that would deterministically catch this bug.

Similar problems cropping up in https://bugs.webkit.org/show_bug.cgi?id=65063 because the underlying issue - casting to BitmapImage - isn't limited to this one case.
