[1.7.6] Deflect Projectiles defies enemies' attempts to cancel it

[Bananadine]

The mindslayer talent Deflect Projectiles (in Psionic/Kinetic Mastery) seems to be immune to enemies' attempts to deactivate it (via a brawler's Combination Kick, a paradox mage's Entropy, or that one thing the Weirdling Beast does, for example). When it tries to turn off, it prompts the player to choose where any nearby projectiles will be sent, and if the player cancels this choice then the talent will continue to be sustained.

It's hard to be certain that this is a bug but it really looks like a bug. I'm most of the way through my current run and I've seen pretty much all my sustained talents get cancelled by enemies except this one. It just prompts me to complete the cancellation and I decline and that's that. I've seen that happen many times but I've never seen the talent actually stop working, except when I actually wanted it to.
