As I wrote in #9702 comment:
There is a bug with vscode code, I am able to fix that by calling editor.getControl().getModel().applyEdits(..) twice, But it's not a real solution, What should I do?
Look at this - references text is shown only after applying the next edit in vscode:

Untitled-1.ts.-.vscode.-.Visual.Studio.Code.2021-07-08.19-37-11.mp4

@EstherPerelman given that it is for test purposes, perhaps you can perform multiple edits with a comment mentioning the behavior in vscode? If multiple edits are required for the codelens to appear for references I'm not sure what else we can do.

I do notice the same behavior as you, however, if the method is proper from the start it will display the codelens when restarting the app:

export function foo(): void {
    return;
}
