Popups should emit an event when they are closed.

Hi @mapsam . How can I listen to it?

    map.on('popup.close', function(e) {
        alert();
    });

doesn't work

@nibygro try listen to it this way:

let popup = new mapboxgl.Popup()
popup.on('close', function(e) {
    alert()
})

[nibygro]

It is working but pupup close event fire twice when open and close.

[kds-snyder]

I am seeing the same as @ansarikhurshid786; the popup close event fires for a new popup when it is created, if I removed an existing popup before creating the new popup

I am also seeing popup.on('close', ...) fire on creation, and then twice on close.

@nibygro try listen to it this way:

let popup = new mapboxgl.Popup()
popup.on('close', function(e) {

})
