The script does not work well with the newer cinema mode #94
Description
YouTube seems to have overthought things, and cinema mode is starting to resemble full-screen mode, with the scroll effect loading suggestions for other videos instead of the description or comments section.
Is it possible to personalise the variables (values), so that it no longer clicks ‘enable cinema mode’?
Violetmonkey feature? I don't see that thing in Tampermonkey, probably zero chance in Greasemonkey, ScriptCat, or FireMonkey.
Apparently you can detect what cinematic mode someone has by looking at the SVG icon:

</svg>I think the A/B test on my account has ended, so I can't help you create another mechanism for enlarging to full screen windowed without clicking.
