Description

When fully expanding all of the nested groups in each row of a grouped list, scrolling down to the bottom causing the scroll bar to jump up and down in an infinite loop.

Reproduction

2. Fully expand all of the groups in the list
3. Click and drag the scroll bar to the bottom of the list

Actual Behavior

The scrollbar quickly jumps up and down, in an infinite loop. View attached screen recording to see this behavior.

Expected Behavior

The scrollbar should remain stationary in the position that it was left in. No bouncing is expected.

@mihir0 Can you try using GroupedListV2 -- it fixes this specific issue.

Example usage is here: https://developer.microsoft.com/en-us/fluentui#/controls/web/detailslist/groupedv2
