VS Code Remote SSH does not allow attribute macros to provide correct intellisense hints

OS: Manjaro 21.2.0 (Linux Kernel 5.13.19-2)
Remote OS: Fedora 32 (Container Image) (Proxmox 6 LXC Linux 5.4.143)
VS Code: 1.62.3
Rust Analyzer: 0.3.827, nightly
Rust (remote and local): 1.58.0-nightly (936f2600b 2021-11-22)

With the following macro:

use proc_macro::TokenStream;
use quote::quote;
use syn::{parse_macro_input, DeriveInput};

#[proc_macro_attribute]
pub fn m(_meta: TokenStream, input: TokenStream) -> TokenStream {
    let input = parse_macro_input!(input as DeriveInput);

    let ident = input.ident.clone();

    TokenStream::from(quote! {
        #input

        impl #ident {
            fn new(_: String) {}
        }
    })
}

When the macro is imported into another rust project (not workspace) on a local machine (files mounted via CIFS share)

When accessed via VS Code Remote SSH

Not particularly world ending for me, but thought I'd post here for anyone encountering this.

Reproduce the attribute macro m example in a project outside the workspace, comparing local access with VS Code Remote SSH against the listed Rust Analyzer and Rust versions. Trace why the generated new method is available locally but not shown in remote intellisense; done means the remote view provides the same correct hint.
