Scrollbar disappears when scroll to end with arrows

Hey guys,
Have weird bug with scroll bar, the scrollbar disappears when clicking next button past the very last slide - so it’s visible until you scroll click-next past the end (turning of looping did not help, even before I applies CSS styling it was doing the same). If you tap one more time it reappears when it reloops.

Any ideas how to fix?

Self-solved:

Set CMS container overflow to scroll this prevented from over scrolling and making bar dissapear, then added this bit of custom code to hide y overflow bar that I got stuck with:

.yourdivcontainername { overflow-y: hidden; } .swiper-container.swiper1 { overflow-y: hidden; }
