Notification.permission in chrome always return denied

Question

I have a website that asks notification permission from user during log-in. I have a code there that auto-logouts the user when he/she denies the permission (see the codes below)

//Checks if user browsers notification is "Allowed", if "denied", logs out user
if(Notification.permission == 'denied') {
     removeAllCookies($cookies);
     $location.path("/login");
}

That code seems ok at first but just today it started malfunctioning. All new users auto-logouts even if they haven't configured the permission yet.

I even tried to check the permission manually at the favicon at the left of address bar and I can see that it is still set to ask(default). I also tried to manually set it to Allow yet the Notification.permission function still returns denied. What's causing this? It is ok in my pc but in all other users it auto-blocks.

EDIT: Just now I'm already experiencing the same thing on my PC. My Notification permission is Allowed but Notification.permission always return denied. I console logged it and it really does return denied. Anyone?

are you loading the permission inside an iframe? Seems like a chrome change, where Notification.permission will return denied if asked within an iframe

If you are using in CodePen or JSFiddle, where code is running inside an iframe, the permission will always return denied on Windows and Linux. On macOS works fine.

The ability to call Notification.requestPermission() from non-main frames had been removed from Chrome since version 60, but still works fine on Firefox at time of writing.
