Caster Mastery - Open Chest when you Cast a Spell Doesn't Work with Triggered Spell

Hello,

It does not work when you link cast when channelling support skill.

My exact combo is :
-Divine Ire
-Cast when channelling support
-Lightning Blink
(-Less duration support)

The main issue here is that it the passive does not work.

However if it is possible to maybe fix this too... It was mention before but the same passive open chest in Heist with normal spell, also work on Strongbox and it is quite dangerous and maybe makes the passive unusable.

And I think it does not work with Echo Support (as I usually have to cast so many time my spell to open the box with a rate of 25%) but I am not sure.

Thank you for reading.
