When only showing errors/warnings/messages for the current file, sometimes messages are cryptic when split between files

Hello all, I erroneously submitted some bugs to LazyVim about this, but it should be reproducable in any editor that supports showing only problems in the current file.

Given this main file:

mod definition;
use definition::*;

fn main() {
    call(3);
}

My definition with this content:

pub fn call(a: String) {
    println!("{}", a);
}

I will get this errors while looking at definition.rs:

function defined here rustc (E0308)

If I select it, it won't lead me to the problem area which makes it extra confusing. Is there a way to make this more helpful?

Reproduce the issue using the main file and definition.rs examples, then inspect the diagnostic shown when viewing only problems for definition.rs. Trace how the cross-file Rust error is presented and navigated; done means the message identifies the relevant problem clearly and selecting it leads to the useful location.
