@OpalLagoon52 - I've taken the liberty of changing the title of your card to reflect the actual card. Both should be the same so you and others can search for it especially when it's buried among the numerous other ones. In the future, you can change this yourself by selecting Edit Media above your card.
Demo's should be published in a topic on the forum, not here. That allows some discussion too, through which you would have figured out this is not new. I think this trick should be discouraged. It's not intuitive and annoying to execute. Because of this, if this setup is present in a level, players are unable to determine whether it's intended or a cheat.
