Vanilla entities with the component "is_spawnable" in true through behavior packs doesn't work if in the apk game files is in "false" 

Steps to reproduce:

1. Enable the addon in your world
2. Then, load or create your world
3. Check the spawn eggs category in the creative inventory

Expected results:

With the attached pack in this report, the game should add the spawn eggs of the following entities:

1. Arrow
2. Egg
3. Snowball
4. Splash Potion
5. Thrown Trident

Obtained results:

The game doesn't allow to have nothing of the spawn eggs of mentioned entities 

I enlarged the attached file with a resource pack in it to check that the error is still present
