The bug
When you have a repeating command block (command: kill @e[type=falling_block]) and you let an anvil (sand/gravel/dragon egg) fall on the ground it doesn't fall, only the texture disappears. So it is still there as a ghost block (you can't walk through). When you update the anvil by placing a block where the anvil was before it appears, floating in the air.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.
Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. We will reopen it as soon as the requested information has been delivered.
Confirmed for 1.8.2 pre-4. The entity will disappear immediately, and you can't walk through where it was. The impassible area is where the entity was when it died, not where it would have landed. Reloading the world fixes the bug, and causes the block to appear. It will not update, and will remain floating.
I cannot reproduce the texture disappearance in 1.17. The block texture doesn't disappear in Avoma's video either. Have I misunderstood this issue?
@Marcono1234 Seems this is related to: MC-151488
This must have been fixed at some point. It happens in 1.18 but doesn't in 1.19, so somewhere in between.
I'm on 23w04a and cannot reproduce, the blocks are killed and disappear.
This has been fixed along with MC-72248.
Confirmed for 14w21b
Also happens with all FallingSand entities like sand, red sand, gravel and dragon egg
