Looks like we can move extendedRange into the if expression and then wrap the following ~8 lines of code inside the if statement instead.
That way, we make exactly one call to selectedTelephoneNumberRangesChanged.

I'm teetering back and forth between the two options, because I prefer the early return but at the same time having two calls to selectedTelephoneNumberRangesChanged is kind of annoying. That said, there's another early return that calls selectedTelephoneNumberRangesChanged above, and I would never make this change to that one, so I think I'm going to keep it consistent. Thanks for your help and review!
