`node:test` custom reporters get `test:stdout` and `test:stderr` events before `test:dequeue`

What steps will reproduce the bug?

Create a folder with these files:

index.test.mjs:

import { it } from "node:test";

it("test", () => {
  console.log("message from the test");
});

reporter.mjs:

import util from "node:util";

export default async (source) => {
  for await (const event of source) {
    if (event.type === "test:stdout") {
      console.log(event.type, util.inspect(event.data.message));
    }

    if (event.type === "test:dequeue") {
      console.log(event.type, event.data.name);
    }
  }
};

and run

node --test --test-reporter=./reporter.mjs

which will print

test:dequeue index.test.mjs
test:stdout 'message from the test\n'
test:dequeue test

How often does it reproduce? Is there a required condition?

It always does the same

What is the expected behavior? Why is that the expected behavior?

I expected test:dequeue test to be printed before test:stdout 'message from the test\n' as the documentation states "Emitted when a test is dequeued, right before it is executed."

What do you see instead?

The test:stdout event is emitted before the test:dequeue, which makes it impossible to understand which test was running when the message was written to stdout.

Empieza ejecutando el comando indicado con index.test.mjs y reporter.mjs para reproducir el orden de los eventos. Lee el manejo de reporter-event de node:test test_runner y añade cobertura para este caso; se considera terminado cuando test:dequeue sea observable antes que test:stdout para la salida de esa prueba, de acuerdo con la semántica documentada.
