Have you installed the PNG file in the location expected by the SVG
file?  Alternatively, you can adjust the embedded file name in the SVG
file.

For example, I saved the two files as /tmp/foo.svg and /tmp/foo.png and
edited the xlink:href attribute in /tmp/foo.svg to point to
/tmp/foo.png (a relative file name also works).

The result renders fine in Emacs 25 and 26 (w/ ImageMagick), Emacs 27
and 28 (w/ Cairo and w/o ImageMagick), as well as Firefox 86.0.1, with
the system librsvg 2.50.3:

So maybe the issue is in locating the embedded file?
