Maw of Mischief Minion Explosion and Assassin's Mystical Infusion

It seems like Assassin's mystical infusion ascendancy node applies the crit chance to channeling part of the skill but not the minion explosion. This doesn't make sense because the channeling part doesn't even do damage so it should be the hit part that is getting the bonus however it doesn't seem to work like that.

Also it looks like the rune of the angler in pob accurately shows that the minion explosion has 100% base crit and I don't know why that wording works but the assassin node doesn't.

Hopefully this gets changed because I really wanted to do a crit version with Maw of Mischief.
