The HTML is using the picture element to allow fallback from SVG to PNG:

<source srcset=fronting.svg type="image/svg+xml">
<img src=fronting.png alt="A schematic diagram...">

It would be nice if the way Tor Browser disabled SVG was compatible with this usage, to allow the browser to try PNG next.

On the other hand, I see the MDN page says these API are experimental, so go ahead and close this if it seems esoteric or unsupported.

Isn't a server side solution?
#20314 a good client side solution, in my opinion.

We should think about supporting that fallback in #20314. Closing this ticket as a duplicate.
