Shadow of Demise Capstone Feat Doesn't Working as Described

One of the benefits of the Shadow of Demise feat is that a TR's stealth meter will no longer be interrupted while regenerating. This currently does not work as per the SoD description. It used to work (prior to the 1.1 patch), however it's currently functioning like the TR's base stealth regeneration mechanism. I've tested it in multiple scenarios, including normal exploration zones, Heroic Encounter zones, and normal and epic skirmishes and dungeons. If I am hit while my stealth is regenerating, not only will regeneration pause, but my stealth meter actually goes down relative to the amount of damage I take. I do seem to still get the increased stealth regeneration speed benefit of the feat, not to mention its core massive damage boost, but the uninterruptable regeneration definitely isn't working.

EDIT: Ugh... can't correct the grammar in the title. Should say it isn't working...
