Edit: You can omit the reproduction steps I've provided and reproduce this by simply selecting a cape in the dressing room.

In the latest preview, you'll possibly encounter this new content log error if you exit a world and head to the dressing room:

[Molang][error]-minecraft:player.0.persona-19747a2db20c4ed7-0 | | query.armor_texture_slot can only be used when an entity context is provided.

This is fully reproducible in vanilla minecraft without any RP/BP enabled.

Steps to reproduce:

1. Activate the Content Log GUI and create a new world.
2. Join the world, then save and quit.
3. Head back to the start menu.
4. Click to view the Dressing Room.

Observed results:
You'll see a content log error.

Expected results:
No content log errors should be thrown.
