When you try to blow up the light block using TNT or anything destructive, the light block would be gone, and also drop itself when you put multiple light blocks. This doesn't match with other technical blocks such as barriers and command blocks. This also doesn't match Java Edition behavior.
Step to Reproduce
1. Place down a few light blocks (emitting light or not, it's up to you)
2. Place a TNT right next to it and ignite it.
3. Observe.
Expected Results
The light block doesn't drop or be destroyed.
Observed Results
The light block gets destroyed, even drops itself.
Confirmed. Drop chance!
