faze through blocks at head height or when you jump and it your head on a block you will jump into that block and start suffocating

a block at head with no block below it you can walk into and you will start suffocating as well as when you jump and hit you head on a block and i am reporting this because a lot of people are going to be mad if the do this with bedrock or obsidian and can't get and the might loose all of their stuff
