Web App URL Handlers

Through the web app manifest, developers can configure a PWA to register for URL handling. If a matching HTTPS link from an associated web origin is activated in another application or the OS, this feature allows Edge to prompt the user to continue navigation with that PWA. A new PWA window is opened to handle the incoming link navigation. The developer must configure the web origin to acknowledge the web app association by using a .well-known/web-app-origin-association file.

This polyfill will give developers early and frequent access to test the latest API shape and ergonomics for PARAKEET with test & prod data traffic while also allowing us to iterate quickly and address any changes needed prior to making this a part of the web platform natively.
