Bug description

When autoHeight is enabled, and slidesPerView is "auto" the height is not updating on the last slide, if the last slide is less than 2/3 of the swiper container (not wrapper). If the last slide is more than 2/3 of the swiper container, the height is resizing as it should.

Here's an image when it works as it should (last item is more than 2/3 of width), and all four lines are displayed:

Here's an image when it does not work as it should (last item is less then 2/3 of width), and only 3 lines are displayed (previous slide has 3 lines):

Expected Behavior

When swiper is swiped to the last slide the height of the container should reflect the last item height, not the second to last item.

Actual Behavior

If the last slide is less than 2/3 of the swiper container (not wrapper), the height does not update.
