Issue with SVG containing "url(#)"

[suryasanchez]

Hi,

When trying to generate an image with a SVG background-image that containes "url(#...)", I get an error 404 not found.

Probably because the SVG contains something like this:

Expected Behavior

Image generated correctly

Current Behavior

Missing SVG background. When the SVG content includes "url(#)".

It looks like the package wants to fetch the url where it's not existing because it's related to the current SVG.

And then the error like GET http://localhost:3000/%23a 404 (Not Found) await in toSvg (async)

Possible Solution

Handle url() where the ref is inside the SVG.

Steps To Reproduce

Use this SVG as background-image, try to use it as Background Image in a HTML node and generate the image.
