Flipper is banned at Disneyland apparently

I went Friday (Anaheim) and had mine in my backpack because thats where it usually is. Going through the bag check, the guy saw it and called his supervisor over. Supervisor or whatever he was told me that according to Disney, this is now a banned item/device and I needed to remove it from the property despite it not actually being listed on their website of prohibited items. I’ve gone multiple times before with it as well. Just a heads up.
