The Bug
When using a respawn anchor in a void world it can sometimes create ghost blocks when it explodes.
Replicate
Get a Respawn Anchor to full power in Void World
Blow it up (May have to do it a few times to get the effect to happen)
Fly around in exploded area
Notice that there are some ghost blocks
Note
It does not happen 100% of the time

It's not restricted to void worlds, and the respawn anchor doesn't need to be fully charged. You can immediately fix the issue by placing a block in that space, but then the block you placed is lost and the ghost block returns to what it was before the explosion.
Void Worlds were the easiest way to find them when I was testing it. I didn't test MC-175177 on it yet so for the time being they should remain as separate tickets.
Does MC-175177 include your issue?
