LSP Client no longer sends textDocument/hover after version 0.200.4

[DeityLamb]

Summary

LSP Client no longer sends textDocument/hover after version >=v0.200.4

Description

For some reason, the client stopped sending the textDocument/hover request to the LSP after version 0.200.4 (0.199.10 works).

Steps to reproduce:

1. Install zed >=v0.200.4
2. Install some non-built-in extension (java for example)
3. hover to something

Expected Behavior:
hover works
Actual Behavior:
hover doesn't work :(

I am not able to reproduce (but don't currently have Java configured).

1. Are you seeing this in all languages/lsps? e.g. is hover in your Zed JSON settings working (json-language-server)
2. Can you look at "dev: language server logs" -> RPC Messages and see whether Zed's hover requests and jdtls responses are flowing as expected.
3. Would you be willing to do the git bisect and see if you can identify the offending commit between v0.199.0-pre and v0.200.4 which broke things? Dev builds for zed are pretty easy to setup, see: Zed Docs: Development on Linux. After installing the pre-reqs it's just cargo run --

1. JSON LSP works fine
2. Version 0.200.4 doesn’t send hover requests at all, 0.199.4 does
3. Seems related to this commit 🤷‍♂️

In 0.200.4, the hover provider is registered dynamically, and for some reason hover requests are not being sent afterward
