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 https://searchfox.org/wubkat/rev/12fc92585a259a29b2522e7e902492be45a57b6a/Source/WebCore/html/canvas/CanvasRenderingContext2DBase.cpp#1468-1492
