Minecraft snapshot 24w12a introduces the max_stack_size item component which allows the creation of oversized stacks than what is normally possible. Since oversizing seems to now be a supported feature, I would expect all behaviors to support oversized stacks. However, filled buckets such as water and lava do not support this behavior, leading to item loss when using the max_stack_size item component.

Steps to reproduce

1. Run the following command: /give @s water_bucket[minecraft:max_stack_size=8] 8
2. Place the obtained water bucket.
3. Notice that the result is a single empty bucket, rather than 7 water buckets and 1 empty bucket as expected
