Hi Telerik Support,

the scrolling and pagination does not seem to work in Firefox anymore. Is there any workaround?
in Chrome and Edge it works just fine!

if i click on an Pagenumber or Next Page or sth. like this, there happens nothing.
if i try to scroll the scrollbars showing up and changing their size, but they doesnt scroll.

i have also tried to scroll here:
