Table With Virtual Scroll and Multiple Frozen Columns - Scroller Unstable

[jcosgravebdo]

Describe the bug

When virtual scroll is enabled on a p-table and multiple columns use pFrozenColumn, vertical scroll becomes unstable and will jump around automatically upon scrolling down and then back up.

Environment

Angular 18.1.0 application

Reproducer

https://stackblitz.com/edit/stackblitz-starters-yhh7be?file=package.json

Angular version

18.1.0

PrimeNG version

17.18.0

Build / Runtime

Angular CLI App

Language

TypeScript

Node version (for AoT issues node --version)

20.14.0

Browser(s)

No response

Steps to reproduce the behavior

1. Go to https://stackblitz.com/edit/stackblitz-starters-yhh7be?file=package.json
2. Scroll the top table (Broken Scroller) to the bottom and then try to scroll back up.
   2.1. You will either be blocked completely from scrolling or the scroller will jump around
3. Scroll the bottom table (Working Scroller) to the bottom and then try to scroll back up.
   3.1 This works as expected

Expected behavior

Both tables should scroll without jumping. 1 frozen column + virtual scroll works, but when adding 2 or more frozen columns + virtual scroll, the scrolling behavior is unstable and unusable.
