Shadow Step / Dark Theory Inconsistency

TamboRhyyn

I use the Xbox Series X version of the game. When normally leaving a boon's range that has both Shadow Step and Dark Theory, both effects linger for 2/3/4 seconds. However, when the boon is snuffed while in its range, Shadow Step continues to linger for 4 seconds, but Dark Theory is immediately canceled. Is this intentional?
