If you are unable to provide a video, can you please add steps you took to reproduce this issue, along side some screenshots showing those steps?

Additionally, please ensure you are playing on a vanilla client as two blocks occupying the same space is very unexpected for the vanilla game.

This actually duplicates MC-82010 and I think it should be resolved as such to avoid further unnecessary reopening in the future. See the resolution of issues such as MC-158965
