Items drop from shulker box when broken.

Put the summary of the bug you're having here

What I expected to happen was...:
Usually break loaded shulker box with silk touch pickaxe, and store loaded box in my inventory.

What actually happened was...:
Breaking the loaded shulker box causes the shulker box to break and all items are spilled out. Items then must be retrieved instead of them being held inside shulker box.

Steps to Reproduce:
1. Launch 25w02a
2. Load a world that has a loaded shulker box.
3. Place shulker box, inspect contents, then break with silk touch axe. (silk touch not normally required)
