+             then selection gets drawn underneath the color, so you can't see
+             the selection.
+
+             This is due to the fact that the div containing the selection is
+             absolutely positioned with a z-order of -1, and so is drawn
+             below EVERYTHING else that doesn't have a "position" property.
