[css-paint-api] HTML spec switches on CanvasImageSource

[asajeffrey]

In https://drafts.css-houdini.org/css-paint-api-1/#drawing-a-cssimagevalue we have:

The CanvasImageSource typedef is extended to also include the CSSImageValue type to be used as an image source.

The spec doesn't say what to do in the cases where the HTML spec matches on CanvasImageSource values, for example https://html.spec.whatwg.org/multipage/canvas.html#the-image-argument-is-not-origin-clean.

Is the intention that such cases should always be treated in the same way as HTMLOrSVGImageElement?

@asajeffrey (sorry for the delay).

Yes that is the intention. There was originally a pull request for the HTML spec for this (but didn't make it in as only 1 impl at the time). I believe there is an issue in houdini drafts to "patch" the HTML spec in the paint API for this. But I'll keep this issue open until I do this.
