Invulnerable paintings disappear

The bug

When you merge Invulnerable:1b data of paintings with a command, bigger ones disappear (not killed, just being invisible). And some smaller ones turn into items.

How to reproduce

1. Place a few big and small paintings on a wall
2. Set Invulnerable:1b:

   /execute as @e[type=painting] run data merge entity @s {Invulnerable:1}

3. Some paintings pop off, others get invisible
