[Rust-analyzer] Code blocks on datatips (hover to type/ hover to doc) doesn't highlight

[GrayJack]

I noticed a while that code blocks on datatips (hover to type/ hover to doc) doesn't highlight like RLS since I started using RA. Maybe it's possible to look into that since RA became the official LS.

Yep this isn't ideal. rust-analyzer uses a different (also valid) way to provide this as markdown, whereas RLS would send sort of {lang:"rust", text: "let foo = 123"} kind of thing.

r.a is sending something like {markdown:```rust\nlet foo = 123\n```}. This is supported, I'm not sure why atom isn't using the indicated syntax highlighting. It'll need to be investigated in atom-languageclient.

I noticed that this package is using your fork of atom-languageclient. Should I open a issue on your fork repository?

I'll raise an issue with main branch, I was going to provide an LSP message example. In general I want to try to work with the semi-dead upstream as much as I can, ie I have prs for all my patches.
