Since the URL has a fragment, this will always be treated as an SVG mask
with an external resource document containing a <mask> element. There is no
need to determine whether the image is an SVG image.

Why? The value of mask-image is "url(image.svg#id), url(image2.svg#id)".
Both are interpreted as references to SVG <mask> elements. There's no
problem.
