Hi Blink owners, We'd like to extend the Conditional Focus experiment. It is currently running m102-m105, and we'd like to extend by 3 additional milestones, making it m102-m108 (inclusive).
Contact emailselada...@chromium.org Explainerhttps://github.com/WICG/conditional-focus/blob/main/README.md Specificationhttps://wicg.github.io/conditional-focus Design docs https://docs.google.com/document/d/1LHJRt-ry9hwzFTbPxKrmD0VvtEFEU6lvqsD7k6wwGKM Summary Extend the getDisplayMedia() APIs to ensure that tab-capture and window-capture return a new subclass of MediaStreamTrack called FocusableMediaStreamTrack. This new subclass exposes the focus() method. This new method allows Web-applications, when capture starts, to decide whether the captured tab/window should be immediately focused, or whether the capturing tab+window should remain the focused one.

Reason this experiment is being extended 0. Some relevant background: Originally, this feature ended up ready and in Origin Trial quite some time before our partners were ready to take advantage and participate in the experiment. The OT was therefore *shifted* and *restarted* multiple times, eventually landing on the range of m102-m105. Our partners are now ready and have started rolling out code taking advantage of this feature - so far internally within their organization, and soon to the general public. 1. More time is required for our partners' deliberate rollout to reach more users, allowing these partners to provide more accurate, battle-tested feedback. 2. Mozilla and Apple have both engaged positively with the proposal (see here <https://github.com/w3c/mediacapture-screen-share/issues/190>). Mozilla has made a proposal <https://docs.google.com/presentation/d/1ulgTHkHcpUa7FBtPHYYsUL1ATjO1meRmW5ghB9ELDXg/edit#slide=id.g12b1145f5f6_9_8> for a general change to getDisplayMedia(), and suggested that the API shape of Conditional Focus should be altered to fit that new shape. The added complexity of tying Conditional Focus to adjacent API changes prolongs the time to finalize Conditional Focus. While this is ongoing, we should keep supporting partners who have invested engineering time in this OT. We are therefore requesting extension by 3 milestones, making the experiment run for m102-m108 (inclusive). Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? Supported on all Desktop platforms, but not on any mobile platforms.
