Description

scrollbug

This is from the demo here.

Steps to reproduce:

  1. Scroll all the way to the bottom, so that firstPage is 1 and lastPage is 4.
  2. Scroll all the way to the top. It helps if you go slowly once you reach the top.
  3. When the new data is loaded (firstPage becomes 0), the scroll position jumps up a page.

Contributor guide

Research direction
Inspect the scroll event handler in the infinite scroll directive to identify why the scroll position jumps upward when new data loads at the top. Focus on the logic that adjusts the scroll position after prepending data.
