- [x] Rule out weird spacing in the markdown
- [x] Check if it's the unusual title text (`"#9"`) in the markdown IT TOTALLY IS

) and this is more text after the link.

For that to be a normal hyperlink like always.

Resultata

It tried to show the raw markdown instead of turning it into "<a href" etc

Thanks! It would be nice if this could fail loudly. Not sure if that's worth the trouble, but I guess it'd be nice to at least know why a title attribute with contents #9 breaks things in the first place.
