Off Canvas Scrolling

I love this plugin! However, I have an issue with animation triggered by scrolling when.

For animations that either enter from the side or from the bottom (i.e. slide in, slide up) the browser allocates space for them outside of the webpage from the direction they are coming from. In other words, it expands the webpage with white space beyond the webpage borders.

So for “on scroll” triggered animations that slide in from the right side, a scroll bar is present at the bottom of the browser that lets you scroll sideways to the right outside of the webpage content area until you scroll down past that animation.

And for animations that slide up in my footer, it creates white space at the bottom of the webpage beyond the footer.

Is this a bug that can be fixed?

Thank you in advance!
