Description

According to Service Worker specification https://w3c.github.io/ServiceWorker/#control-and-use-worker-client, workers should inherit controllers for blob URLs. Currently, only DedicatedWorkers inherit the controller, while SharedWorkers do not.

This policy is temporary and will be removed in a future update.
