Bug description

Hello,

I have a straightforward setup that causes an unusual issue with Swiper. Although I've reviewed similar reported issues, this case includes additional properties that seem to disrupt the slider functionality. In the reproduction link, you can see that adding:

loop: true,
slidesPerView: 'auto',

Causes weird behavior of the Swiper slider, even though the loop option is enabled, it won't loop to the slides.

To make things ever worse, adding centeredSlides: true sets the last slide as first!

So I thought, adding more slides via loopAdditionalSlides: {number} could fix this, but it made things even worse.

I believe that you should reconsider the implementation on this crucial part, as it clearly has issues in it.

Otherwise, Swiper is the way to go, so thank you for maintaining such a wonderful library.
