The Bug:

Players without operator permissions cannot normally interact with blocks inside spawn protection, however, you are able to rotate items within item frames, regardless of whether or not they're inside spawn protection.

Steps to Reproduce:

1. Start a server, join it, give operator permissions to yourself, and switch into creative mode.
2. Set the world spawn to your current location by using the command provided below.

   /setworldspawn ~ ~ ~

3. Place down some item frames and some items within them.
4. Switch into survival mode, remove your operator permissions, and grant anyone else with them in order to activate spawn protection.
5. Attempt to rotate the items within the item frames.
6. Take note as to whether or not you can rotate items within item frames in spawn protection.

Observed Behavior:

Items within item frames can be rotated.

Expected Behavior:

Items within item frames would not be able to be rotated.
