Shulker's boxes can be opened by blocking with some blocks (Caves & Cliffs)

Summary:

Shulker's boxes can be opened by blocking with some blocks.

The list consists of blocks added in the Caves & Cliffs.
I will also update depending on the release of new blocks and changes in the Java version.

Blocks that are not blocked by the shulker box:

• Powder snow MC-220707
• Small dripleaf MC-220708
• Cave vines MC-220709
• Hanging roots MC-220710
• Spore blossom MC-220711
• Glow lichen MC-220669

Steps to reproduce:

1. Place down a shulker box.
2. Block the shulker crate with the indicated blocks.
3. Attempt to open the shulker box.

Observed results:

The shulker will open and the lid will go into the indicated block.

Expected results:

Shulker boxing will be blocked (at least with Powder snow for sure, and with the rest of the blocks - let Mojang decide).
