Ionic2 on-tap disables content scroll

In my Ionic2 app, I have an on-tap event on a div inside the block. The page is larger than the viewport and therefore should scroll. However, when trying to scroll by touching the div with the on-tap event the page doesn’t move (it does move when scrolling outside the div).

<ion-content>
    scrolls
    <div on-tap="tapped()">
        doesn't scroll
    </div>
    scrolls
</ion-content>

Does the on-tap event stop event propagation all together?

What am I missing?

(Using (tap)=“tapped()” instead as in the docs doesn’t help.)
