Bug description

When setting slidesPerGroupAuto to true, the slides are only progressing correctly when navigating in the "previous" direction. when clicking in the "next" direction, the slides progress one by one.

Expected Behavior

the slides should progress the same way no matter what direction you choose to slide.

Actual Behavior

the slides progress differently depending on the direction you slide. when going backwards, it works correctly. when going forward it seems to ignore the setting or maybe calculate the slides that are in view incorrectly.
