code snippet to reproduce:
So I noticed when I swap from branch use_one_tt_for_a_derive to branch to-from-cfg_attr-assist this has happened with other branches. But this is my most recent example
That Rust analyzer will start saying a bunch of functions have incorrect parameters and incorrect fields In the file crates/hir-expand/src/db.rs.
Even after restarting the server this continues to happen. It seems I have to completely restart VS Code. So it might be a bug related to VS Code.
I assume this issue with not be able to be fixed. However, I wanted to bring attention to the issue.

Research direction
Reproduce the issue by switching between use_one_tt_for_a_derive and to-from-cfg_attr-assist in the linked repository, then inspect the false positives reported in crates/hir-expand/src/db.rs. Compare restarting the language server with restarting VS Code; done means branch changes no longer leave incorrect parameter and field diagnostics.
