It is possible to use:

filter: url(#svg-filter-desaturate);

but not:

filter: url(data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A//www.w3.org/2000/svg%22%3E%3Cfilter%20id%3D%22desaturate%22%3E%3CfeColorMatrix%20type%3D%22saturate%22%20values%3D%220%22/%3E%3C/filter%3E%3C/svg%3E#desaturate);
}

The use case this would enable is to define filters inside CSS stylesheets. This would give developers access to a very powerful filter system they wouldn't have otherwise. For example, you could "colorize" with feColorMatrix.

Works on Firefox 76 and Chrome 81.

Probably RenderSVGInline::requiresLayer() const final { return false; }

Simon Fraser, do you think this could be an easy fix?

I am able to reproduce this bug in Safari 15.6 on macOS 12.5 using attached test case and it does show these difference compared to other browsers:

Desaturate, encoded as base64 ----> RED

Desaturate, encoded with "escape()" ----> RED

Turn white to green, encoded with "escape()" ---> Missing completely.

Just wanted to update latest testing results. Thanks!
