No paths shown in completion pop-up with rust-analyzer

[traviscross]

Thank you for the bug report

• I am using the latest version of lsp-mode related packages.
• I checked FAQ and Troubleshooting sections
• You may also try reproduce the issue using clean environment using the following command: M-x lsp-start-plain

Bug description

When used with rust-analyzer, lsp-mode does not show the paths to items in the completion pop-up. E.g.:

Comparatively, eglot does, and this is the behavior I would expect. E.g.:

This is testing with the latest current commit of lsp-mode and the latest commit of rust-analyzer.

Prior to this rust-analyzer PR, lsp-mode does exhibit the correct behavior:

• Improve completion label details display rust-lang/rust-analyzer#15956

But, of course, eglot and other clients seem to work after that commit.

Steps to reproduce

With the most recent commit of rust-analyzer and the most recent commit of lsp-mode, start Emacs with a minimal configuration and open a Rust file. Edit it to contain:

fn main() {
    Pin// <-- Cursor here.
}

Expected behavior

The paths to completion items should be displayed.

Which Language Server did you use?

lsp-rust

In testing, it seems this will be fixed by:

• Do not resolve during annotate, enrich documentation with details (Fix #3201) (Fix #3905) #4625
