Quick succession Divine Ire channelling bug

If I charge up a Divine Ire, let it go, and then immediately go to cast it again the skill will not charge up beyond 1 stage and my character will spam out 1 stage lasers.

To play the skill properly I actively have to *wait* before charging up again otherwise I get nowhere and cannot charge up a new laser.

I am not running out of mana. I am not being stunned. It is incredibly clunky and actively lowers my DPS.

supports are Awakened Lightning Penetration, Inspiration Support, power charge on critical, Awakened Added Lightning, and infused channeling.

bug reference #2201621440

PS. If there were a reduced cast speed support I would put that onto my flame dash, because half the time I use it I dash forwards and then backwards and get nowhere.
