Notes: That property is designed to get around differences in behavior of different browsers, when child elements of ContentPane have relative or absolute positions. It is recommended to enable that property when child controls or parts of html generated by them use position:relative or position:absolute. For example, UltraWebGrid uses position:relative style attribute, and therefore, it may fail to be scrolled in IE or it may go out of tab bounds in other browsers.
