The test should throw, but it doesn't currently.
Firefox returns
Uncaught DOMException: CanvasRenderingContext2D.drawImage: Passed-in image is "broken"
while Safari is completely silent and seems to just go with it.
Probably something to explore around

In addition to

Probably this failure is very similar and could be fixed at the same time.

This now PASS.

But this one needs to be fixed. Probably in a separate bug.
