Ditto. toRenderListBoxIndex should be done inside RenderListBox.

         // The cast to HTMLElement below is safe because the only other possible listItem type
         // would be a WMLElement, but WML builds don't use accessibility features at all.
         if (rect.contains(point)) {
             listBoxOption = m_children[i].get();
             break;
         }
     }
 
     if (listBoxOption && !listBoxOption->accessibilityIsIgnored())
         return listBoxOption;
 
     return axObjectCache()->getOrCreate(m_renderer);
 }
