End crystals don't explode when destroyed by nearby explosions

The Bug:

End crystals don't explode when destroyed by nearby explosions.

If TNT was placed next to one another, and one of these blocks were to explode, the exploding TNT would cause nearby TNT blocks to explode with it. This isn't the case with end crystals.

Steps to Reproduce:

1. Place down an end crystal and some TNT nearby.
2. Ignite the TNT and watch the end crystal closely.
3. Take note as to whether or not end crystals explode when destroyed by nearby explosions.

Observed Behavior:

End crystals don't explode.

Expected Behavior:

End crystals would explode.
