On Java Edition, Mob Heads/Skulls are held properly. On Bedrock Edition, this is not the case. The screenshots I provided show that the heads/skulls are too far to the right and extremely hard to see on Bedrock.
3 Screenshots are on Bedrock Edition, while I provided 2 images on Java.
Conduits have already been reported at MCPE-134436, so I have removed them from this report.
