bugged scaffolding

hello (translate this text in the translator so it may contain errors). Testing the version of minecraft 1.14 I found a scaffolding with scaffolding, you can put more scaffolding than normal and you can put a scaffolding (1 block) in the air and lift them all the time. I did everything on a creative basis. It gives a link to my movie on youtube because the movie weighs 22 mb and to add here can be a maximum of 10 mb.
