[whatwg] Proposal to extend registerProtocolHandler

[Michael Davidson]

For rPH, please don't require a user-initiated click for the call. That's
one very annoying thing about notifications - it takes users two clicks to
enable them, and every app has to find some suitable in-page UI to ask users
to make the first click. Since both notifications and rPH are confirmed by
the UA, it seems silly to require a user-initiated click. Prompting for
permissions is much less annoying than opening a new window, so I don't
think the same standards should apply. It's also very easy for users to
prevent sites from asking in the future by just denying the permission.
