[MC-301139] Items lose their components when their item type changes

When changing the state of the object (for example, a bucket of water -> an empty bucket), all its components (spells, attributes) are lost. This happens in version 1.21.8.

Steps for playback
1. Take an item that has a changed condition (for example, a bucket of water).
2. Rename it to the anvil so that it gets the Minecraft component: Custom_name.
3. Pour water using a bucket.
4. Please note that the subject will change its condition from Water_bucket to Bucket, and its name (component) will disappear.

Environment

Minecraft 1.21.8

The behavior you are describing is a specific interaction, which may or may not be a bug, but it does not infer any particular generic behavior of how things should behave in any situation when the type changes. If you believe particular interactions are wrong, please report specific issues.
