Visualization - Select3D_SensitiveCircle always return infinite depth value in boundary mode

Standard_Boolean Select3D_SensitiveCircle::Matches (SelectBasics_SelectingVolumeManager& theMgr,
                                                    SelectBasics_PickResult& thePickResult)
{
  Standard_Real aDepth = RealLast();
  Standard_Real aDistToCOG = RealLast();

  if (mySensType == Select3D_TOS_BOUNDARY)
  {
    if (!Select3D_SensitivePoly::Matches (theMgr, thePickResult))
    {
      thePickResult = SelectBasics_PickResult (aDepth, aDistToCOG);
      return Standard_False;
    }
  }
  ...

  aDistToCOG = theMgr.DistToGeometryCenter (myCenter3D);
  thePickResult = SelectBasics_PickResult (aDepth, aDistToCOG);
  return Standard_True;
}

The above code will reveal the bug, aDepth value is not assigned if it hit the boundary.
