Another long standing issue similar to MC-265199, but this case with blocks instead of entities.

Players can break or interact with blocks like chests, beds, or any other block outside the spawn protection area, even if there's protected blocks between them. The server doesn't check for this case and validates any interaction done client-side when server-side shouldn't be possible.

How to reproduce

1. Create a void world in a server with a certain spawn protection radius.
2. Give op permissions to someone else aside from you.
3. Place a wall of any low hardness block at the edge of spawn protection.
4. Place a chest outside the spawn protection area, close to the wall.
5. Move inside the protected area, get close to the wall of blocks and deop yourself.
6. Try to interact with the chest by breaking the wall consecutively (you need to be fast).
7. Notice how the server validates your actions.

Expected result
The server wouldn't let you be able to interact with the chest behind protected blocks, even if client-side is seemingly possible.

Observed result
The server validates the player actions in this case, making able to interact with the chest behind blocks in protected areas.
