Steps to reproduce:

Open https://plnkr.co/edit/nbZ6t7UrQjbNUOtJ
Scroll the grid using mousewheel
try to scroll using the vertical thumb

Note: This only happens on Firefox for Windows. Firefox for MacOS is fine.

Actual results:

The scrollbar doesn't move

Expected results:

The scrollbar should move

I can reproduce the issue in Nightly92.0a1 Windows10.
However, if disabled WebRender (i.e, BASIC or Direct3D 11 compositor), the problem is gone.
