💻 Code

// @filename: definition.ts
function X() {}
type X = true;
export default X; // do "find references" here


// @filename: usage.ts
import X from './definition';

X; // this reference is found

async function asd() {
	const a = await import('./definition');
	a.default; // this one is not
	await import('./definition').then((m) => m.default /* this one is not */); 
}

🙁 Actual behavior

This needs the files to be copied into your IDE to reproduce. In VS Code, do "find references" on export default X. You'll see that the references of the indirect export (e.g. function x()...; export default x instead of export default function x()...) are not recognized for dynamic imports (for static imports they are).

🙂 Expected behavior

Recognize references for dynamic imports, too

Additional information about the issue

The playground needs to be copied into real files locally, as the playground isn't multifile-capable (from what I know), but it's needed for this reproduction.

Doing indirect exports is sometimes necessary in order to do declaration merging.

You can do multi-file repros in the bug workbench. See here. From the given information it isn't entirely obvious to me where do you request references and which ones are missing.

TIL! I adjusted the link and description, hope it's clear now
