Specification

No information provided

Summary

Allows Service Workers to delegate their transient user activation (acquired from a user interaction like a notification click) to same-origin client windows. This enables client windows to open child (pop-up) windows, such as email previews or chat windows, without being blocked by the popup blocker. This allows developers to take advantage of frame state-sharing performance, instead of requiring a new top level browsing context (which is what Clients.openWindow does). This also allows 'popup' delegation from one frame to another, making things like 3rd-party auth and payment easier.

Missing feature

Motivation

Partners have directly asked for this feature to allow notifications to not require a full page load from a client if they want to show a popup preview window. Example: Click on an email notification, and an email client should be able to open a lightweight auxiliary (popup) window with the email contents.
