Never mind, I wasn't aware it's already in the game as a tip (or should I say "fip")
Yeah it was there since autoplay was more of a hidden feature but I guess the "fip" is pretty pointless now that autoplay is a normal option too. And yeah it's intentional that toggling it via control isn't permanent but just meant as a "temporary override". Dunno if that really makes much sense though, it could as well toggle it normally.
