I am still experiencing this bug in 9.1.0

For some perspective:
The native prev/next buttons trigger twice, skipping slides, so I had to build my own navigation using swiper.slidePrev() and swiper.slideNext(). Doing that though, beforeSlideChangeStart does not trigger consistently. slideChange does, but with that I don't get the activeIndex of the slide we just left...

EDIT: even using the native navigation, beforeSlideChangeStart will not trigger consistently.

Same on v.11.1.4

Seems it only happens when loop is enabled. Because in that case currentSlide and previousSlide indexes become equal at some point.
One workaround is to set rewind: true instead of loop
