NUnit delayed constraint does not appear to work in playmode test

I'm attempting to check that a condition is met after n seconds. I thought I could use the After method to do this, but it's not working as I expected. Am I doing something wrong here?

The test seems to fail instantly, instead of after delayInMilliseconds.

Using Unity 2019.1.14f1, NUnit 3.5.0.0.

Example:

 // fails
 [Test]
 public void TimePassed_Polling()
 {
     Assert.That(
         () => Time.time > 5.0f,
         Is.True.After(delayInMilliseconds: 6000, pollingInterval: 100));
 }
 
 // passes
 [UnityTest]
 public IEnumerator TimePassed_Wait()
 {
     yield return new WaitForSeconds(6.0f);
 
     Assert.That(() => Time.time > 5.0f);
 }
