Presence of storybook causes `vi.useFakeTimers();` to break.

Describe the bug

I have a test that looks like this:

import { it, vi, expect } from "vitest";

vi.useFakeTimers();
async function waitTenSeconds() {
  await new Promise((res) => {
    setTimeout(res, 10000);
  });

  return 99;
}
it("timer test", async () => {
  const prom = waitTenSeconds();

  vi.runAllTimers();

  const result = await prom;

  expect(result).toBe(99);
});

This test passes by it self.

If I install storybook@10.0.11 then this test will now error.

Note that this test fails immediately, it doesn't wait 5000ms for this error to occur.

If you remove vi.runAllTimers then the test hangs indefinitely.

There are no warnings when you run npm i.

Other dependencies that will also cause this error:

    "@storybook/addon-docs": "^10.1.11",
    "@storybook/vue3-vite": "^10.1.11",

Validations

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.

Reproduce the failure in the linked repository, starting with src/timer.test.ts and the listed Storybook dependencies. Compare the test behavior with and without Storybook installed, focusing on vi.useFakeTimers() and vi.runAllTimers(). Done means the timer test resolves and passes when the reported Storybook packages are present.
