Deepslate can get destroyed by ghasts, which is very annoying. Cobblestone is immune, but deepslate should also be immune since it has more than 4.034 blast resistance.

How to reproduce:
Make a platform out of deepslate
Stand on it
Spawn a ghast
Go into survival mode
See what happens when the fireball hits the platform

What I expected:
The explosions will do no damage

What I saw:
The ghast fireballs started destroying the deepslate platform
