There's a FIXME in the IDL for this: https://github.com/WebKit/WebKit/blob/aef5bd9e27d33901f93a2100ba05f8737801ae24/Source/WebCore/html/canvas/CanvasDrawImage.idl#L26-L37 I came across this while updating this data: https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/drawImage#browser_compatibility If the other data is correct, WebKit would be the only engine to not support this.
