I think this case should be added when clients of |AXNodeObject::Markers()| to
handle it.

         marker_types.push_back(marker->GetType());
         marker_ranges.push_back(
             AXRange(marker->StartOffset(), marker->EndOffset()));
         break;
       case DocumentMarker::kComposition:
         // No need for accessibility to know about these marker types.
         break;
     }
   }
