Why is the 225 baked in here? (I'm assuming it's the animation duration, but doesn't dismiss handle that already?)

Forgot I had this in there.

Yes, the 225 is for the animation. Created a todo to handle the case I was looking at.

You shouldn't need to use whenStable with fakeAsync because the whenStable will just be called synchronously.

I was unable to get my tests working without whenStable, so I will have to dig in more there.

We should do config.duration && cofig.duration > 0 in case someone sets it to null or undefined.

Can we use strict null checking?

We can then use the Non-null assertion operator

for instance in this case it would be:

if (config.autoHide! > 0) {
