On the streamed VNC desktop (xfwm4), Chrome did not hide its toolbar when a
video entered HTML5 fullscreen via 'f' - the window was full-screen (outerHeight
1080) but the tab/address bar stayed, leaving only 988px of content, so the
address bar bled into the Go-Live broadcast.
Toggle Chrome-initiated browser fullscreen via CDP (Browser.setWindowBounds
windowState fullscreen) around the 'f' step. That reliably hides the toolbar
(innerHeight 1080 vs 988); the toolbar is restored on exit, so normal browsing
still shows it. Verified live: clean full-screen video, no toolbar.
