Dark Archangel seemingly triggers a GCD

[TheHate123]

Describe the bug
The sim casts Dark Archangel for Shadow Priests about 12-13 seconds into a pull, and then does nothing for 1 second. I assume it's coded to trigger a gcd which it does not, the spell is off-gcd.

To Reproduce
Steps to reproduce the behavior:

1. Run a sim.

Expected behavior
The spell should not trigger a gcd.

Sim Links and Screenshots

There is a full second between the Dark Archangel at 12.53 and the Mind Blast that I'm hovering.

Yeah for some reason I assumed a gcd here. Will remove that
