Facebook login popup doesn't close after login on iOS8 - facebook

Question

I'm testing my web app login flow on the iOS8. I notice that on iOS8, the login dialogue pops up, but after logging in, it just stays there, showing a blank page.
The login works, because the page behind it shows the user information, but the popup just stays there, while it should close automatically. On iOS7 and iOS6 it does close. On desktop browsers it closes too.
I've tested some other random sites (for example brainfall.com) using FB.login(): same thing.
Does anyone have a fix for this?
Any help is much appreciated!

Check this:
fb_window_redirect
Override de window.open method. This allows you to know what windows are opened.
Then you can redirect the window opened by the FB SDK.
...
window._open = window.open; // saving original function
//Override the function
window.open = function(url,name,params) {
var new_window = window._open(url,name,params);
if (typeof onWindowOpen === "function") {
onWindowOpen(url, name, params, new_window);
}
return new_window;
};
...
var openedWindows = [];
var fbWindows = [];
function onWindowOpen(url, name, params, new_window) {
...
// Filter the facebook oauth request
if (url.contains('facebook.com')
&& url.contains('oauth')) {
fbWindows.push(new_window);
}
openedWindows.push(new_window);
}
...
//On fb login button pressed callback:
FB.login(function(response) {
//Try login
if(response.authResponse) {
//Login succesful
// Fb window redirect.
// see onWindowOpen
var fbwin = fbWindows[0];
var redirect_url = ''
fbwin.location = redirect_url;
}
},
{scope: 'email,publish_stream,user_birthday'});
