Description

i'm using HorizontalInfiniteCycleViewPager in my application with 5 fragments. the issue is when i'm scrolling backwards (only backwards) after 2 scrolls everything is disappeared and i should scroll 5 times again in backwards to reveal fragments again. i'v tried FragmentStatePagerAdapter and FragmentPagerAdapter for my adapter but got nothing.

Research direction
Investigate the adapter implementation and the library's internal scroll logic. Look at the HorizontalInfiniteCycleViewPager source code, especially the method that handles backward scrolling. The issue may be related to how fragments are recycled or removed. Review the 11 comments for any attempted solutions or insights from maintainers.
