Unchecking "Allow websites to ask for permission to send push notifications" in Safari does NOT stop websites asking
On my Mac (running Mohave), in Safari in Preferences > Websites > Notifications, deselecting the option "Allow websites to ask for permission to send push notifications" does NOT stop websites asking me permission to send me notifications.
For example, if I go to this website, https://www.businessinsider.com the website asks me for notification permission as shown in the image below, even though the notification permission option is not selected in Safari preferences.
Why are websites still asking me for permission to send notifications when I have switched off this option?
