[Bug] Table scrollbar not working for nested views in Firefox

When some views are nested (see screenshot below) the tables scrollbar can not be dragged with the mouse in Firefox. In Chrome or Edge, the scrollbar works as expected.
Ignition 8.0.5, Firefox 70.0.1 (64-Bit) on Windows 10
The attached views should reproduce the problem.
