Undefined document introduced when using import.meta.url in worker

[swwind]

Describe the bug

// main.js
new Worker(new URL("./worker.js", import.meta.url), { type: 'module' });

// worker.js
console.log(import.meta.url);

Build result

// main
new Worker(new URL("/assets/worker-f523fd11.js", self.location), {
  type: "module",
});

// worker
(function () {
  "use strict";
  console.log(
    (document.currentScript && document.currentScript.src) ||
      new URL("assets/worker-f523fd11.js", document.baseURI).href
  );
})();

I'm 100% sure document does not exist in web worker and my worker will panic.

I think use typeof document != 'undefined' && before document.currentScript is better
