Markdown Guide misrendering on FF nightly

cryptpad.fr's Markdown Guide: Extensions renders a bit weird on FireFox Nightly for me:

Class diagram is missing and mindmap is in the previous section.

As a sidenote I cannot upload webp which would have been ⅓ the size of png.

Hello!

As mentioned on our Matrix public chat, it's a known issue, please see the following bug report on our GitHub repository.

Regarding WebP, someone was able to send a pull request to support it. Hopefully we'll be able to merge it for the next CryptPad 5.5.0 release. 😊

Have a good day!
