Should top-level await + dynamic import + cyclic import causes "unsettled TLA" error?

[xqm32]

What version of Bun is running?

1.1.31

What platform is your computer?

Darwin 23.6.0 arm64 arm & Debian

What steps can reproduce the bug?

See nodejs/node#55468

Create following files:

• package.json:

{
  "private": true,
  "type": "module"
}

• foo.js:

const bar = await import("./bar.js");
console.log(bar.default);

• bar.js:

import {} from "./foo.js";
export default "It works!";

Then run bun foo.js.

What is the expected behavior?

I don't know, but ONLY JSC based runtime/browser will output "It works!" successfully.

What do you see instead?
