Specification

https://github.com/WICG/document-picture-in-picture/pull/109

Summary

This enables `opener.focus()` from a document picture-in-picture window to bring system-level focus to the tab that owns the document picture-in-picture window. This allows developers to bring the original tab back to the foreground when necessary, e.g. when the user needs to access a more full UI/experience that doesn't fit in the smaller picture-in-picture window.

WebKit: No signal (https://github.com/WebKit/standards-positions/issues/41#issuecomment-1919879502) Added comment to existing standards position issue for document picture-in-picture. No response yet

Web developers: Positive (https://github.com/WICG/document-picture-in-picture/issues/94) We have received feature requests for programmatically returning to the opener tab from multiple first and third-party partners

Other signals:

Ergonomics

N/A

Activation

N/A

Security

While allowing the picture-in-picture window to bring system-level focus to the opener tab at will could be abused, the user gesture requirement effectively ensures that the user is at least currently interacting with that website and not another, so is less likely to be surprised or tricked by the change of focus to another window from the same origin.

WebView application risks

Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?

N/A

Debuggability

N/A

Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).

None expected
