Fix #30076: RenderLayer area blocks mouse scrolling

Browse Source 
In fact all list templates used to block mouse scroll. It's because mouse
scrolls list's scroll bar. But mouse scroll also used to be "eaten" even
if there's no scroll in list template.
This commit makes scroll even be ignored by list templates if there's
no scroll bar on list.
