RenderListItem resets its marker's style on style change even if the diff is StyleDifferenceEqual. This causes high cpu usage on http://www.nokogiri.org/tutorials/searching_a_xml_html_document.html because there is an animation that changes the style every second and the RenderListItem keeps resetting its marker's margin, which triggers a layout and the RenderListMarker re-computes its margin during layout and updates its style again.
