Why does the area boundary of Baidu map cover the cover?

when I draw a boundary partition for Baidu map, the cover on the map cannot trigger a click event

finally, if the official API, does not color the zoning, it will not mask the mask

.

var bdary = new BMap.Boundary (); / / boundaries of administrative areas

  bdary.get(place, rs => {                         //place
    var ply = new BMap.Polygon(rs.boundaries[0], {    //
      strokeWeight: 2,                         
      strokeColor: "Aqua",
      fillColor: ""               //
    }); //
    this.map.addOverlay(ply); //
