The bug

Powder snow now mostly is associated with its bucket item. However, it's still possible to obtain the block in item form. The item form of the block should not exist whatsoever.

How to reproduce

1. Load the attached structure
2. Get the item from the chest

Expected behavior
Chest is empty due to powder_snow being an invalid item ID

Notes

This is a trivial and inconsequential bug, but it would be nice if bedrock handled these things in the same way java does.
