Summary
The latest beta made this change:
Fixed Barrier Block being destructible whilst not holding a Barrier Block.
Which actually makes the functionality harder to use and breaks parity with Java Edition.
Step to Reproduce
1. Place a barrier block (can be obtained with /give)
2. Break it when you're not holding the barrier block.
Observed Results
The barrier block hitbox is hidden and you cannot remove it when not holding a barrier block.
Expected Results
The barrier block hitbox still shows and can be broken, even when not holding a barrier block.
Note: This ticket is related with MC-233769, so if this gets solved as WAI or kept open, that ticket should react too.
This change breaks existing content by allowing players to access blocks/entities behind barriers
