In some WMS service, on getFeatureInfo in geojson the geometrie is null. On that case, when user click on map to show some feature info, we don't have any tag on map to show where the click is made, to show user which feature is selected.
When queryFormat is gml, the feature is select in blue, when queryFormat is html, a blue square appear on map, but when we are in geojson (maybe json too) nothing is show to help user to know which feature is selected.
