Kurgal's Leash support not triggering on additional Disciple of Varashta command skills

The support Kurgal's Leash, which is supposed to grant Unholy Might to both the master and the commanded minion only works on the base command for the Djinns granted by the Disciple of Varashta Sorceress' ascendency.

Ruzhan only triggers it on Command: Ruzhan's Brand
Navira only triggers it on Command: Navira's Embrace
Kelari only triggers it on Command: Kelari's Brutality

Command: Ruzhan's Trap, Ruzhan's Fury, Ruzhan's Reckoning, Navira's Fracturing, Navira's Well, Navira's Oasis, Kelari's Judgment, and Kelari's Deception doesn't trigger the support gem.

Furthermore, Kelari's Malediction comes as a separate minion skill from the Kelari minion skill and while it triggers the gem on using the Sandblast command, the skill tab doesn't update with chaos damage. It's hard to tell whether or not they do get the damage boost when they trigger their explosions, but I doubt they do.
