Summary
In Java Edition 1.15 update, the End Stone Bricks blast resistance was changed to match End Stone. However, on Bedrock Edition, this is yet to be changed.

Step to Reproduce
1. Place down a layer end stone bricks, and also a layer of end stone to compare.
2. Place down a TNT on each of those layers and blow it up.
3. Compare both layers.

Expected Results
The end stone bricks layer should have the same crater size as the end stone does.

Observed Results
The end stone bricks layer has a larger crater size compared to the end stone layer.
