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


What's preventing the PR from landing?
 



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.

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).
