Fire and soul fire have a hitbox

I can confirme for 20w10a

I hope that it won't be fixed, because it allows us to look at fire as targeted block in f3 menu xd
and also to edit fire with debug stick

Very likely intended as per MC-147708, MC-163655.

Also, this new behaviour brings fire in line with other blocks, so is best kept.

This works as intended.
Even though it isn't mentioned in the snapshot post, @unknown mentioned this in his newest video, so it should be intended.

He mentions this at around 2:19
