Unwanted gesture pass through

[lufixSch]

I'm using a ListView inside a ScrollView for a dropdown menu to select a value. As I understand it, when I scroll through the inner ListView the outer ScrollView shouldn't move. But in my case I'm not able to scroll through the inner ListView without moving the ScrollView.
The ListView is located in it's own component. I recreated the Problem here: https://play.nativescript.org/?template=play-ng&id=0gJqNQ&v=2
I encountered a similar issue in iOS with the native Datepicker where the Swipe is passed through to the parent elements.
Did I misunderstood how and when gestures are passed through or is this a bug?
