_{Unable to reproduce 20w21a.}

_{@tkasriel from discord said he was able to reproduce in 20w21a. "That bug is reproduceable if you are standing on the .7 mark of a block".} 

@Andrew369 You have several mods installed in your reproduction video. Can you reproduce the issue in vanilla without any mods installed?

If this still works without mods in the latest version, please make another report.
