Jumpy ion-slides

Hello guys !

Question about ion-slide-box :
On the page where is my slider, I need to have a bounce (has-boucing=true works fine). But when I slide
manually, I have a weird effect with the bounce of the page.
Do you know how to deactivate the bouce when I scroll (horizontally) the slider ?

Here’s a codepen if you want to see : http://codepen.io/catslover/pen/NqKBdR (try to change the left and bounce a little bit at the same time, it’s more sensitive on mobile devices)

I hope to be clear.

Thanks everybody!
