Scrolling doesn't work with swipable cards

[TWiStErRob]

1. Open https://googlechrome.github.io/ui-element-samples/swipeable-cards/ in Android Chrome
2. Start scrolling down by touching

If the touchdown happens on a card, the code captures it; but if the touchdown is outside a card on the background, it works.

You can delete evt.preventDefault(); from onStart() function. This will solve the problem to some extent.
