Origin and Destination input boxes stay opened when setOrigin/setDestination are called twice.

[andrewQwer]

Hi.

When setOrigin or setDestination are called 2 or more times input boxes stay opened, suggesting to select a location. I would like to behave as if it was initially set.

Example is here:

Screenshot:

map.on('load', function() { 
  map.addControl(directionsControl, 'top-left');
  directionsControl.setDestination("Philadelphia");
  directionsControl.setOrigin("New York");    


  setTimeout(() => {
    directionsControl.setDestination("Chicago, Illinois, United States");
  }, 2500);
  setTimeout(() => {
    directionsControl.setOrigin("Washington");
  }, 5000);
});

It doesn't happen when I pass coordinates, but I would like to see place names instead of numbers in input boxes.

Any workarounds to keep it closed?
