Profane Bloom interruption

This passive ability is amazing for the most part.
But it literally stops some of the build enabling chain reactions of builds that are likely to pick Profane Bloom, such as Essence Drain builds.

Logic tells me that it should in fact not work like this and actually do what the Contagion gem suggests:


"If an enemy dies while being affected by Contagion, it spreads"

The same interaction is true in practice with using Vaal Detonate Dead.
The chain reaction stops if a mob procs Profane Bloom.

This is not true for Vaal Ice Nova though. Or else I can't tell :)
