MC-269633 is not fixed for powder snow buckets. Using an overstacked powder snow bucket replaces the entire stack with a single bucket. However, this issue does not occur when the bucket is used by a dispenser or on a cauldron.

Steps to reproduce

1. /give @s minecraft:powder_snow_bucket[minecraft:max_stack_size=99] 99

2. Place powder snow using it in survival mode

Expected behavior: The powder snow stack size should decrease by 1, and an empty bucket should be placed in an available inventory slot, similar to how it works with water and lava buckets.
Observed behavior: The 99 powder snow buckets were replaced by a single empty bucket, causing a loss of 98 items.
