What steps can reproduce the bug?

Run bun test with the following contents in foo.test.js:

// foo.test.js
import { afterEach, beforeAll, beforeEach, describe, test } from "bun:test";

describe("timeout bugs", async () => {
  beforeEach(async () => {
    await new Promise((resolve) => setTimeout(resolve, 200));
  });
  afterEach(async () => {
    await new Promise((resolve) => setTimeout(resolve, 200));
  });
  test(
    "first test",
    async () => {
      await new Promise((resolve) => setTimeout(resolve, 200));
    },
    {
      timeout: 220,
    }
  );
  test(
    "second test",
    async () => {
      await new Promise((resolve) => setTimeout(resolve, 600));
    },
    {
      timeout: 1000,
    }
  );
  test(
    "third test",
    async () => {
      await new Promise((resolve) => setTimeout(resolve, 1000));
    },
    {
      timeout: 1300,
    }
  );
  test(
    "fourth test",
    async () => {
      await new Promise((resolve) => setTimeout(resolve, 1000));
    },
    {
      timeout: 0,
    }
  );
  test(
    "the only test that should actually time out",
    async () => {
      await new Promise((resolve) => setTimeout(resolve, 1000));
    },
    {
      timeout: 100,
    }
  );
});

What is the expected behavior?

All tests, except for the last test, should succeed:

foo.test.js:
✓ timeout bugs > first test [203.10ms]
✓ timeout bugs > second test [601.91ms]
✓ timeout bugs > third test [1002.49ms]
✓ timeout bugs > fourth test [1004.94ms]
error: Test "the only test that should actually time out" timed out after 100ms
✗ timeout bugs > the only test that should actually time out [103.41ms]

 4 pass
 1 fail

What do you see instead?

% bun test
bun test v1.1.8 (89d25807)

foo.test.js:
✓ timeout bugs > first test [203.33ms]
error: Test "second test" timed out after 1000ms
✗ timeout bugs > second test [442.58ms]
✓ timeout bugs > third test [1002.92ms]
error: Test "fourth test" timed out after 0ms
✗ timeout bugs > fourth test [1302.32ms]
error: Test "the only test that should actually time out" timed out after 100ms
✗ timeout bugs > the only test that should actually time out [103.78ms]

 2 pass
 3 fail
Ran 5 tests across 1 files. [3.07s]
