Steps to reproduce the problem:
1. Open the following link in a new tab http://itemslide.github.io/ 
2. Navigating back/forward should not be possible in this tab because it's new so the navigation history is empty
3. Try to use trackpad horizontal scrolling to scroll the horizontal div with cards - it should work!
4. Open the same link (http://itemslide.github.io/) from an existing page
5. The back button should now be enabled (it should be possible to navigate back in the tab's history)
6. Try to use trackpad horizontal scrolling to scroll the same horizontal div back and forward - it will no longer work! Scrolling back will send 1 scroll event to the div, and all the following events will go straight to the "back action animation" (the black semi-circle with an arrow that indicates a back action will be triggered once the scroll gesture is released)

What is the expected behavior?
Calling preventDefault on scroll events should prevents horizontal scrolling from triggering back/forward actions, this is an important feature as it allows developers to use horizontal scrolling in horizontal timelines, carrousels, etc.

What went wrong?
This behavior suddenly stopped working, and now there seems to be no way to capture horizontal scrolling in an element without triggering navigation actions if they are available - i.e.: if there are pages to navigate back/forward to

Did this work before? Yes Probably 64
