IsEqualTo does not handle double.NaN correctly

[PhilippNaused]

[Test]
public async Task Test1()
{
    await Assert.That(double.NaN).IsEqualTo(double.NaN);
}

Result:

AssertionException: Expected to be NaN
but found NaN

This is a regression compared to v0.67.19
This doesn't happen with float.NaN
