FB.ui method share does not return callback when using Facebook Mobile Browser

Question

let promise = new Promise((resolve, reject) => {
     FB.ui({
         method: "share",
         href: href,
         ref: ref,
         hashtag: hashtag,
         quote: quote
     }, function (response) {
         console.log(response);
         if (response !== undefined && !response.error_code) {
             return resolve(response);
         }

         return reject(response);
     });
});

Nothing happens after the user hits the share button on the facebook mobile browser...

The callback function isn't triggered.

How to reproduce: Shared my site on facebook, clicked the link that came up on the facebook app. That opens up the Facebook Mobile Browser and click the button that triggers the javascript I've mentioned. The share dialog opens up above this, I click share, it goes away and nothing else happens.
