Markdown and links are not friends

[Hywan]

Steps to reproduce

1. Write the following message:

   https://some.link1/_/lol and https://some.link2/_/bar
   

2. And send the message.

Outcome

What did you expect?

I expect to see 2 links, and zero emphasize.

What happened instead?

I have 2 broken links, and emphasize between /lol up to link2/.

The Markdown parser considers _ as an emphasize marker, instead of being part of the URL.

It happens also in Element Web. Not tested on Android.

It seems that the formatted body is "formatted_body": "https://some.link1/<em>/lol and https://some.link2/</em>/bar" which would point to this being a Rust side bug coming from here https://github.com/matrix-org/matrix-rust-sdk/blob/main/bindings/matrix-sdk-ffi/src/timeline.rs#L50C8-L50C43

Indeed, I ended up in Ruma, which uses pulldown_cmark. I'll raise the bug there.

Closing this issue, as it's not a bug, it's just how CommonMarkdown is defined.
