Svg with data URI embedded image losing image after conversion

[artfulinfo]

Hello

After constructing an SVG with the following format:

svg = """\
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="{} {} {w} {h}" width="{w}" height="{h}">
    <path id="cropPath" d="{d}" />
    <clipPath id="crop">
        <use xlink:href="#cropPath" />
    </clipPath>
    <image xlink:href="data:image/{ext};base64,{encoded}" clip-path="url(#crop)"/>
</svg>
""".format(xmin, ymin, w=width, h=height, d=path.d(), ext=ext, encoded=encoded)

After converting with:

cairosvg.svg2png(
            bytestring=svg, write_to=f'./{p}.png', background_color=None, unsafe=True)

It returns a black filled version of the shape cropped with the clipPath, but the image is not kept. After searching through some of the other issues, I attempted to install the other dependencies recommended (Pillow and the css specific ones); switching to using xlink:href rather than href and enabling unsafe mode, with no success.
I think the docs mentioned support of all of the approaches I'm using in the svg construction, and I have run out of ideas to try.
I've confirmed saving the exact same string to disk with the below works fine as expected:

with open(f'./{p}.svg', 'w') as file:
            file.write(svg)

To test, I checked what the svg2svg output was and no image is present:

<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="120pt" height="100.8pt" viewBox="0 0 120 100.8" version="1.1">

Hi,

Is this a duplicate of #383?

[artfulinfo]

In my case it does not work regardless of whether unsafe flag is enabled or not. But could potentially be related. Is there any more information I can provide to help that I left out in the first comment?

Yes. Could you please share a SVG file generated from your template? If it contains personal data you don’t want to share publicly, you can send a mail.

Sure thing, just shared over email

It’s fixed, feedback is welcome!
