I upload [this .svg](https://raw.githubusercontent.com/marionebl/svg-term-cli/refs/heads/master/examples/parrot.svg) to my post as I would any other image

Here is what I see in the preview:

If I open the .svg directly in my browser (visit [https://raw.githubusercontent.com/marionebl/svg-term-cli/refs/heads/master/examples/parrot.svg](https://raw.githubusercontent.com/marionebl/svg-term-cli/refs/heads/master/examples/parrot.svg)) or view it on GitHub (here in the README.md for example: [GitHub - marionebl/svg-term-cli: Share terminal sessions via SVG and CSS · GitHub](https://github.com/marionebl/svg-term-cli/tree/master)), it is rendered properly.

.svg is enabled as an upload type and I don’t think there is an issue with the size of the .svg.

I took a quick look, and it seems that after uploading an SVG, the content inside `<defs>` is gone.

 ![The image shows the interface of an XML or SVG editor with code snippet on the left and a rendered result on the right. (Captioned by AI)](https://global.discourse-cdn.com/meta/original/4X/f/d/5/fd5473bf5dbbcff44b0ac8060d62c27cc9e03e65.png)

`symbol` is not on the whitelist, that’s the reason:

Now, it works:

![The image shows a Telegram download link in the chat with the filename "parrot(1)6231x0 (upload://fKaLFUt9RBvAWJoEpo5TVv0)", leading to a direct link to a hidden cdc file segment.

I don’t think there is an issue in allowing it. 🤔
