Beacon item can be destroyed by an explosion

The bug

Nether stars cannot be destroyed by explosions, and beacons are made with a nether star. So why can beacons be destroyed by explosions?

Steps to reproduce

• Throw a beacon and a nether star on the ground
• Place some TNT nearby
• Ignite the TNT
  → Notice how the nether star item is not destroyed by the explosion, but the beacon is, therefore indicating that beacon item entities can be destroyed by explosions.

Expected Behavior

The expected behavior would be that beacon item entities cannot be destroyed by explosions.
