Scripted attempts to open a popup window after requesting fullscreen would likely be blocked by user agents that do not implement this feature, even if they implement the basic Multi-Screen Window Placement API.Gecko: No signal (https://github.com/mozilla/standards-positions/issues/636 <https://github.com/mozilla/standards-positions/issues/636>)WebKit: No signal (https://lists.webkit.org/pipermail/webkit-dev/2022-May/032223.html <https://lists.webkit.org/pipermail/webkit-dev/2022-May/032223.html>)Web developers: Positive (https://bugs.chromium.org/p/chromium/issues/detail?id=1233970 <https://bugs.chromium.org/p/chromium/issues/detail?id=1233970>) This functionality is requested by a prominent API partnerErgonomicsThere is currently no way to detect feature support before attempted usage; seehttps://docs.google.com/document/d/1RRlGQharWVnmxKTomfKhNiaeE31L7iXHeXVfifOvwJA/edit?pli=1#heading=h.vu2lz7aeddz6 <https://docs.google.com/document/d/1RRlGQharWVnmxKTomfKhNiaeE31L7iXHeXVfifOvwJA/edit?pli=1#heading=h.vu2lz7aeddz6>Activation Developers can make immediate use of this API enhancement.
