Grant Invisibility

I was thinking about taking grant invisibility on my forcefield mastermind to get my pets up over the softcap. However, I was looking at the power on City of Data, and I noticed that the defense portion of the power has a "Cancel on Attack, HitByFoe, MissionObjectClick" tag, which I think means the power stops providing defense when the target attacks or is attacked. This seems to run counter to the description of the power; does anyone know if grant invisibility actually gives a defense bonus to a character in combat?

If I remember right, Grant Invis works the same way as Stealth. The DEF bonus is one value before attacked/attacking, and suppressed when attacked/attacking.

Except under the stealth listing, there's two bonuses, one which is tagged "Cancel on Attack, HitByFoe, MissionObjectClick", one which isn't. Grant Invisibility doesn't appear to function the same way.
