Description
Describe the bug
I'm using a DataTable with a VirtualScroller inside a div with display: "none", and the DataTable does not appear when I remove the display: "none" style.
It looks a bit similar to https://github.com/primefaces/primereact/issues/7516.

Steps to reproduce the behavior
- Go to https://stackblitz.com/edit/znxq12ml?file=src%2FApp.jsx

- The table dos not appear
Notes:
- If I change to
useState(1);to first show the table "tab", it does appear, but if I click the "1" button and then the "2" button is disappears once again. - If I remove the VirtualScroller option everything works fine.
Expected behavior
The DataTable should be visible.

Research direction
Start with the linked StackBlitz reproducer and its src/App.jsx, then inspect the DataTable and VirtualScroller behavior when the component begins inside a display:none panel. Verify the case by switching between buttons 1 and 2, and consider the issue done when the table becomes visible after panel changes while VirtualScroller remains enabled.
