[Table]: Issue with scroll in TableVirtualizer

[Qcyk]

Bug Description

Hi,

I've found a problem with the TableVirtualizer component. Rows aren't rendering correctly when scrolling up. I only noticed the issue in Chrome (it works fine in Edge).

I attached a short video with issue on you Slack channel:

Hi @Qcyk I saw the video, but I can't reproduce the issue either on my Mac with Chrome 142 (or Safari). My colleague also couldn't reproduce it on Windows. Could you please try again with the new Chrome?

Hi today I updated Chrome to: Version 142.0.7444.60 (Official Build) (64-bit). The problem is still the same. You can try selecting a row and pressing the up arrow on your keyboard. The problem with rendering is the same.

I also installed Chrome Canary (version for developers) newest version of Chrome and there scroll works correctly (same as on Edge).
