1781265 - Consider introducing a new WebExtensions waitUntil API method

Status: NEW

(WebExtensions :: General, enhancement, P3)

Description

[Luca Greco [:rpl] [:luca] [:lgreco]]

As part of investigating improvements and tweaks to the event page lifetime policy (Bug 1748534 and Bug 1771203) we are considering introducing a new API method modeled after the ExtendableEvent's waitUntil method exposed in the web content service worker (and used for the DOM events that are able to spawn an active service worker, e.g. ExtendableMessageEvent, FetchEvent, PushEvent and NotificationEvent.

The new method is meant to allow the extension to explicitly signal to the UserAgent that some asynchronous work have been started in response to a WebExtensions API event which may still be in progress and may require extending the lifetime of the background extension content to allow that work to complete.
