Bug description

Based on my example, it appears that some of the slides are applying a positive X transition when the data-swiper-parallax-x is negative and then they suddenly revert and start going correctly.

Expected Behavior

This may be expected behaviour but I was hoping that as the slide progresses from right to left, the child with the data-swiper-parallax-x attributes will transform in relation to the position of the slide on the page.

Actual Behavior

Some slides work as expected, others will move child in opposite direction and then revert after a certain point of the screen.
