Makes it easier to understand that expect does indeed have a separate timeout.
```
Error: expect(received).toHaveCount(expected) // deep equality
Expected: 0
Received: 1
Call log:
- expect.toHaveCount with timeout 500ms
- waiting for selector "span"
- selector resolved to 1 element
- unexpected value "1"
- selector resolved to 1 element
- unexpected value "1"
- selector resolved to 1 element
- unexpected value "1"
