While Iframe works once @allowfullscreen and @webkitallowfullscreen are set, this is not true for a frame inside a frameset. 2263026 1 fred.wang 2026-10-12 23:52:33 -0700 This is actually working if you set Permissions-Policy: fullscreen=* in the HTTP header: https://people.igalia.com/fwang/webkit-bug-95402/frameset.html But I'm not sure that should be the case. At least Chrome and Firefox don't allow that. See also https://github.com/whatwg/fullscreen/issues/112
