Starcaller not proccing for Animate Weapon of Self Reflection

I tried Animate Weapon of Self Reflection with the new Starcaller axe. The animated axes gain the extra damage as a random element, and are able to inflict elements on critical hits - I'm seeing ignites, shocks, and shattering corpses from freeze. But they are not triggering the lvl 20 Starfall from the axe itself.

Seems to me like something that should work, as it would make for a cute meme build. The weapon text reads "Trigger Level 20 Starfall on Melee Critical Strike", and the animated axes are making melee strikes, no? But it clearly only procs on YOUR melee strikes.

I tried with a Ngamahu's Flame axe as well, and those animated weapons did not trigger any flame bursts.

Sad times for Animate Weapon of Self Reflection.
