Character creator cannot load character with items unlocked and equipped in the same Microsoft account on a different device/user profile

Any time you equip an item in the character creator that has to be downloaded, the character simply will not load on another device or another user profile on the same device even though you are signed into the same MS account. Instead of checking whether you own the item and then downloading on that profile/device, it just refuses to let you edit the character. It will, however, allow you to delete the character. This is especially problematic when young family members share an MS login across different profiles on the same device, or on different devices. It also makes users who move to new devices have to recreate their characters.

Steps to reproduce

1. Log in to a Microsoft account in Minecraft.

2. In the character creator, unlock an item via purchase or achievement.

3. Equip the item.

4. Exit Minecraft.

5. Log in to another user profile on the same device, or go to another device.

6. Open Minecraft and log in to the same Microsoft account as in step (1).

7. Try to use or edit the character you made in step (3).

Expected result

Minecraft would let you use or edit the character you created because you are logged in to the same Microsoft account. Since you own the item that was equipped in step (3), it would download the item to the new profile/device if necessary to be able to load the character.

Observed result

"Failed to load character <X>". The "Reload" button does nothing, but "Delete Character" works.
