When investigating the blast resistance of End Stone, I noticed that it's resistance seems lower against TNT explosions than in other versions.

Steps To Reproduce:

• Create a 3x3x3 cube of End stone with TNT in the centre
• Ignite the TNT
• Notice that most of the End stone will be destroyed

The pattern of End stone that gets destroyed in the PC version is quite different, with 99% of the end stone blocks destroyed being directly adjacent to the TNT.

The TNT explosion in MCPE is similar to the effect on Diamond blocks, leading me to think that End Stone has the same blast resistance of 30.
