Early Design Review: Partitioned Popins

[arichiv]

こんにちは TAG-さん!

I'm requesting a TAG review of Partitioned Popins.

A new web primitive is needed to cover short-lived popup use cases which require access to storage partitioned by the popup opener. This primitive should be private and secure by default, while providing a consistent UI experience across user agents. To solve this need, we propose the “Partitioned Popin”, a type of pop-up for loading web content with two unique new features: a modal-like UI relative to its opener tab and cookies/storage being partitioned to its opener context.
