    Description

      Based on this sample code:

      Item {
        Plugin {
          id: mapPlugin
          name: "osm" 
        } 
        Map {
          id: map 
          anchors.fill: parent 
          plugin: mapPlugin 
          center: QtPositioning.coordinate(48.79, 2.14) 
          zoomLevel: 14
      
          MapPolyline { 
            id: mpl 
            line.color: 'red' 
            line.width: 10 
            path: [ 
              QtPositioning.coordinate(48.79, 2.14), 
              QtPositioning.coordinate(48.79, 2.145),
              QtPositioning.coordinate(48.795, 2.145)
            ]
          } 
      
          Button { 
            text: "addPt"
            onClicked: { 
              mpl.addCoordinate(QtPositioning.coordinate(48.78, 2.12)) 
            }
          }
        }
      }

      First you get this display "Capture d'écran de 2018-02-26 15-17-30.png" => correct

      After hitting the button "addPt" you view "Capture d'écran de 2018-02-26 15-17-34.png" => incorrect (1st points is swapped)

      If you provide directly the coordinate (48.78, 2.12) at the end of the path definition, the display is directly the wrong one.
