Description

I'm observing a wrong scroll / displayed items when scrolling up from the set initialScrollIndex.
When the top shown value is say 5, and scrolling up, I expect to see the 4, 3, 2 etc., not 12, 11, 10...

The chosen container size, number of items, item height and initialScrollIndex in the demo code may seem picked random but the issue occurs given those for some reason. And only on desktop Chrome. No issue with desktop Safari.
