"Property change notifications (property-changed events) aren't fired when
the value changes as a result of a binding from the host"
(see https://polymer-library.polymer-project.org/2.0/docs/about_20).
To workaround this problem, we fire the event from the observer.
In some cases this fire the event twice, but our code is
ready for it.
