javascript - window.open() is blocked by browser when is called from promise

Question

I have code like this:

window.open('https://api.instagram.com/oauth/authorize/',
'_blank',
'width=700,height=500,toolbar=0,menubar=0,location=0,status=1,scrollbars=1,resizable=1,left=0,top=0,modal=yes');

This works fine when is called from any place of code, but when I use it in promise (see below), it is always blocked by browser. Any suggestions?

action().success(function (r) {
  // window.open(...);
}

Promises are from angular.

            var newTab = $window.open('', '_blank');
        promise
            .then(function () {
                var url = '...';
                newTab.location.href = url;
            });
