failing test diff is flipped since version 0.32.1

[Nilegfx]

Describe the bug

the following test:

import { describe, test, expect } from 'vitest';

describe('rejects', () => {
  test('buyApples throws an error when no id provideds', async () => {
    // toThrow returns a promise now, so you HAVE to await it
    await expect('abc').toBe('abcd');
  });
});

has different failing diff/results for version 0.32.0 and 0.32.1. 0.32.0 is the correct expected results (at least to me)

0.32.0 results (correct)

AssertionError: expected 'abc' to be 'abcd' // Object.is equality

  - Expected  - 0
  + Received  + 1

  - 'abcd'
  + 'abc'

0.32.1 results (incorrect)

AssertionError: expected 'abc' to be 'abcd' // Object.is equality

- Expected
+ Received

- abc
+ abcd
