Hi! We are changing our Parser, and some rough edges are still around.

This is kind of related to https://github.com/RocketChat/Rocket.Chat/issues/26642

Thanks for pointing this out!

Hi there,

I just started using RocketChat recently, I noticed the un-render issue with the "main" chat. I wonder if there is any update on this.

I'm also new to open-source development, if there is no one currently working on this, can I get some guidance on how to fix the un-render issue? I would like to work on this.

The bug is still present in 6.2.10. Very annoying.

Seems to be present in version 6.4 as well.

It's not a bug, our message parser does not support this YET.

Of course it’s a bug, for two reasons:

• it used to work in the past
• claiming markdown support but then not supporting basic syntax features is by definition a bug.

As for

our message parser does not support this YET

JFC, why do you need to reinvent markdown parsing? There are only an estimated 900 million parsers already.

Still triggers me writing nested list in code block in 6.4. @hugocostadev , is there any ETA to fix that?

It's not a bug, our message parser does not support this YET.

If not support this yet, mention it on official doc is better.

I'm still running into this issue as of 6.9.2.
