Hi,

The problem :

I noticed that, when a creeper or a TNT (or a bed in dimensions) explode, the explosion will reach all entities-block in its native maximal radius, ignoring walls, floors, and even indestructible blocks between the source of the explosion and the entity-block itself.

How to reproduce :

1. Create a wall of obsidian / bedrock, or other blocks that can contain an explosion.

2. Place a creeper or a TNT on a side of the wall, and an armorstand or an itemframe in the other side. They must be separated by ~10 blocks max.

3. Fuse and make explode the creeper / TNT.

4. The armorstands / itemframes on the other side will break, even if there is an indestructible / restisting obstacle between the source of the explosion and them.

I'm pretty sure this bug as already been reported, but it is annoying since several years now, and I couldn't find the issue on Jira, so I decided to report it whatever. Sorry if it already exists.
