[MC-218529] Ghost block in single player world

I was making a redstone machine and I tested it and I got the mysterious ghost block that happens on servers but it was singleplayer. You can recreate it by loading 20w08b and making a singleplayer. Follow my video and build it exactly how I build it and step where I step (sorry for video quality, had to lower dimensions because of the file size limit, higher quality here https://www.mediafire.com/file/6i1rnrs1znozusu/2021-03-09+19-06-11.mp4/file)

I also found that anytime you one tick a piston, it makes a ghost block near it. to replicate, run a one tick pulse into a piston and step in front of it

Ghost blocks are a bug anyway, they're not supposed to be exclusive to servers; in fact, they aren't, they're a case of client-server desync. Singleplayer worlds still get them

I can't seem to reproduce this issue in 1.17.1. With that being said, please provide some steps on how to go about reproducing this. Additionally, attaching some extra screenshots or videos whilst the F3 debug screen is enabled, would also be greatly appreciated. Thank you 😃
