Can't mix items in any of the new recipes

The fix for MCPE-65391 was handled improperly.

You can mix all regular planks when crafting a chest, but cannot mix any of the nether planks. This applies to ALL new recipes added in this beta.

 

How to reproduce

1. Use a mix of oak and birch planks to make a chest
   →  It works
2. Use a mix of oak and crimson planks to make a chest
   →  It doesn't work

Suggested fix

Do what Java added back in 2017 to solve this very problem:

• Allow multiple items for a single key
• Add custom block/item tags (groups)
