How to reproduce the issue

First of all thank you for forking rust-tools, your approach to plugins is really nice, hopefully this fork will live long!

I found the repo following the bug where multiple instances of RA were spawned. Thanks for fixing that so fast!

I found a "bug" in the Rust HoverActions, previously on rust-tools, the syntax highlighting with themes and TreeSitter (correct me if I'm wrong) was used. Now when I hover functions the text seems plain and it's not parsed by the theme which uses TS.

Would be nice to maintain that as it's clearer when reading rust-docs.

Let me know if this is intended and there should be flagged as enhancement instead of bug.

Expected behaviour

Actual behaviour

The minimal config used to reproduce this issue.

Open a rust project and hover a documented function such as tracing_subscriber

Hmm, that's strange - it works on my end (I know that's not a very helpful comment 😄)

Your first screen shot looks like it's Neovim's built-in hover UI (there are no actions).
I did add a new config (that defaults to true):

vim.g.rustaceanvim = {
  tools = {
    hover_actions = {
      replace_builtin_hover = true,
    },
  },
}

I guess if you set that to false, you'll have the old behaviour back.
But I did configure hover actions to use tree-sitter highlighting (they didn't before, iirc).
I do this by setting vim.bo[bufnr].ft = 'markdown'. But I've only tested this with Neovim nightly. Maybe it doesn't work in Neovim 0.9.4?

I'll have to try and reproduce it...

Can reproduce with Neovim 0.9.4.
