Player heads lose their name after being placed

The bug

Since player heads are tile / block entities and thus can save NBT data (just like shulker boxes, bee hives, chest, etc), they should retain their name after being placed. However, this is not the case.

To reproduce

1. Run

   /give @s minecraft:player_head{SkullOwner:violine1101}

   (or use another player name of your choice)

2. Rename the head using an anvil
3. Place it
4. Break it in survival mode
   → The name changed back
