/**
* Runs `trigger` while intercepting the content permission prompt it causes, so
* that we can inspect the nsIContentPermissionRequest without any UI being
* shown.
*
* @param {Function} trigger Requests a permission, e.g. by calling
* Notification.requestPermission(). May be asynchronous, but must not wait
* for the request itself to settle.
* @returns {Promise<object>} The intercepted permission type and the value of
* nsIContentPermissionRequest.hasValidTransientUserGestureActivation.
