I'm working on an application that has an in-app browser based on Chromium. I need to allow a user to interact with a certain web page/server (that I don't have internal access to) through this browser. Some interactions, like clicking on specific buttons, fail with the console message "Uncaught ReferenceError: Notification is not defined". From what I can surmise, this means the server is trying to send me a notification using the Notifications API, but my browser doesn't support it. I've confirmed that !Notification evaluates to true and "Notification" in window evaluates to false. I've also checked for window.chrome.notifications, window.webkitNotifications, and any other kind of notification module that I could find evidence of on the Internet. Nothing related to notifications is loaded, as far as I can tell.
On Firefox, there's apparently a setting that causes Notification to never be loaded at all. I'm hoping that's what's happening here, but I can't find any evidence of such a setting in Chromium browsers, much less how to disable it.
How can I allow Chromium to recognize Notification?
