[BUG] Scroll out of control in TableVirtuoso on Chrome/Edge/Firefox

[eywin]

We use TableVitruoso to render a huge grid in our system. We have a lot of columns and around 10000 rows.
A few weeks ago we started noticing a bug where if you scroll down a bit, the grid goes into freefall and scrolls to the bottom.

It only happends if you horizontally scroll the first column out of view.

I've recreated the bug here: https://stackblitz.com/edit/stackblitz-starters-cub9gb?file=src%2FTableComponent.tsx

To trigger the bug:

• scroll a bit to the right so the entire "first"-column is out of view
• scroll down

I'm not sure if our way of using the TableVirtuoso component is wrong or if this simply is a bug in the component.

The bug is most porminent in Chrome in my tests (scrolls to the bottom), in Firefox it only partially scrolls out of controll (jumps down a bit then stops). I have not been able to trigger it in Safari. Tested on both Windows and Macos.

The bug is also possible to trigger on the Mui-example in the docs. Just add a few more columns and set width to a small enough size that you can scroll the first column out of view.

Any help would be greatly appreciated!
