Immolating Weapon and Divine Fury are not overwritten if casted while active
Immolating Weapon, Divine Fury, and possibly others are inconsistent with other short-term buffs. If you cast them while the effect is active, the buff is not overwritten, thereby wasting your mana.
This inconsistency has been around forever, so I thought I'd log it. I'm aware of other buffs that have more deliberate handling which prevents you from casting the buff altogether while the effect is active, but the handling of these two seems accidental, unless there's some historical context that I'm missing.
