List jumping when new items are loaded

[jakub-wisniowski-widelab]

Hi, I'm using ng v14, ngx-infinite-scroll v13.1.0

When I scroll quickly to the bottom of the list, new elements are loaded and the list jumps down - sometimes by only 1-2 items (that's acceptable) but sometimes by 10 items. I would expect this behaviour:

• user scrolls to the bottom
• new items are loaded
• scrollbar's thumb goes up (to reflect new items below) but items in the viewport stay the same

I tried the solution from this thread it's a bit better but still not perfect - setting interval to 2000ms mostly fixes the problem with jumping, but scrolling gets laggy.

Here is the stackblitz: https://stackblitz.com/edit/ngx-infinite-scroll-kiwalq

Is there any way to fix it?
