Stop tap propagation

I have an item that should perform an action when tapped, but it also contains some content that does something else when tapped.

<ion-item (tap)=edit()>
  Your item here
  <button (tap)=delete()>Delete</button>

So if you tap “Delete,” then edit should not fire. However, there doesn’t seem to be any $event that gets passed to tap, so $event.stopPropagation is not an option.

Is there any way to tap an inner element and prevent that from triggering a tap event on an element that contains it? I don’t want to use click because of the click delay.
