Not _might_. _ **Must** _. Functional code in a `propertyChange` event that is not within an `if` block that checks for the correct `propertyName` is _ **always** _ wrong. (By "functional", I mean it does more than just debug logging or printing.)

Most troublesome is any such code that unconditionally sets a bindable property on the source component -- that will trigger infinite recursion.
