Keyboard navigation does not work in Firefox 65.0.1
While attempting to implement Keyboard Navigation for one of our RadGrid controls, we discovered that this navigation (Arrow Up/Down and Page Up/Down) did not work correctly in Firefox (though it did within IE, Edge, and Chrome). We also tested the Firefox Keyboard Navigation within the Telerik Grid Demo Site, and experienced the same behavior.
Issue can also be observed with the Grid - Keyboard Support
demo using Firefox 65.0.1
Do you know how to resolve this issue, or of any workaround?
