Battlemage Cry triggering on weapon swap

So, I'm experimenting with a melee/caster Scion. I have my first set of weapons as an axe and shield, and I have my second weapon set as a mace and bone shield. My Battlemage's Cry is socketed on my axe. When I swap from set II to set I while moving, my character behaves just fine. If I swap from set II to set I while issuing a move command, my character will stop and use Battlemage's Cry, even when my LMB slot is on Move Only.

Steps to reproduce:
1. Have two weapon sets, with Battlemage's Cry socketed on one of the two sets.
2. Swap to the opposite set (so, the one without Battlemage's Cry).
3. Swap back, and left click on the ground at the exact moment.
4. Repeat and experiment with Move Only, any other skill, or even Battlemage's Cry on Left Mouse Button.




EDIT: This sometimes occurs while I am holding down LMB, but doesn't seem to happen all the time.
