When fixing this, I plan to include (possibly-evolved-a-bit) versions of those 3 testcases as WPTs, along with similar tests for <embed>, <svg:image>, SVG-as-a-background-image-with-`background-size`, etc.

When fixing this, I plan to include (possibly-evolved-a-bit) versions of those 3 testcases as WPTs, along with similar tests for <embed>, <svg:image>, SVG-as-a-background-image-with-`background-size`, etc. (in all cases having width and/or height set to `0` on the `<svg>` element, but nonzero width and/or height on the embedding context).
