Furnace Piston Glitch

Hello, I have just found a bug that is kind of minor for an average Bedrock player, but pretty major for a redstone player. Whenever you push a furnace into another piston or block, the piston that was pushed in will disappear. This may also apply for things like chests and dispensers but I am not sure of that. Thank you for taking this into consideration and I hope you acknowledge this bug enough to fix it
