Native scrolling and android bounce

when I set $ionicConfigProvider.scrolling.jsScrolling(false); and build for android, the bouncy edges appear when swiping on the X axis.
If I set $ionicConfigProvider.scrolling.jsScrolling(true); everything works and there are no bouncy edges.
Is this a known bug?

has-bouncing has no effect when using native scroll.

I am on Ionic 1.2.4 and using crosswalk

Thanks & Cheers
