while trying to upgrade from ionic 3.9 to ionic 4-beta i encountered an inconsistency what is not documented in the Breaking changes.
in ionic 3 the event would propagate after a while if the button was long pressed
<button ion-button (press)="doSomething()">long press"</button>
but in ionic 4 no event is fired
<ion-button (press)="doSomething()">long press"</ion-button>
am i mission something?
