corfu-popupinfo doesn't work with rust-analyzer

[interacsion]

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

Maybe related to #4591? When I try to invoke corfu-popupinfo it's saying No documentation available for 'application_id(...)' (or any other completion symbol). This somewhat works with eglot so I assume it's an issue with lsp-mode.

Steps to reproduce

Enable lsp-mode, corfu-mode and corfu-popupinfo-mode, get corfu to show completions, select a completion and invoke corfu-popupinfo using M-t.

Expected behavior

A new child frame shows the documentation of the selected completion.
