[MC-63811] Silent creeper/TNT didn't work on explosion

when i use the command "/summon Creeper ~ ~ ~ {Silent:true}" summons a silent creeper, but if it explode, the explosion sound will happens.

same issue using "/summon PrimedTnt ~ ~ ~ {Silent:true}"

Linked issues

Might be intentional, as the explosion of a creeper uses the same sound when TNT explodes.

exactly, but if i use the command /summon PrimedTnt ~ ~ ~ {Silent:true}, will happens the same issue

Also happening with falling Anvils:

/summon FallingSand ~ ~ ~ {Silent:1,TileID:145,Time:1}

dying Enderdragons and Splashpotions, they are all not silent

Confirmed for

Silent:1b?

true, 1b, 1, it doesn't matter, it should all work
