Diagnostics not shown in file peek views

[mjbvz]

1. Create two files:

// abc.ts
/**
 * @deprecated
 */
export function abc() { }
abc();

// other.ts
import { abc } from "./abc";

abc()
xyz;

2. With only abc.ts open, run peek references on abc (you can also use the references codelens for this)

Bug
In the peek view, no diagnostics are shown

They are shown with TS 6.0

We don't control this; is VS Code / the LSP client not opening that file and asking for diagnostics?

Yes maybe an lsp issue? cc @dbaeumer
