idk if this bug already appear in 1.21.22 but I am really sure that this bug is not edited and I already tried it without texture pack or any kinds of behavior/resource pack mod but the video that i sent has a mod which is "showing enchant book" idk what the exact name of that but this bug was found in Minecraft Bedrock 1.21.30 beta version. If there's a chance I will try it on current version but i hope this kind og bug doesn't work on current version ;D
