Death's Embrace (Death Domain Power level 8) not applying correctly

[Fransens]

The Death domain power at level 8 makes it so you get healed by negative energy (while letting you get healed by positive too giving you the best of both sides).

o) Channel Energy - Heal Undead heals you.
o) All single-target Inflict spells (Light, Moderate, Serious and Critical Wounds respectively) heal you as well.

However...
o) All AoE target Inflict, Mass spells (again, Light, Moderate, Serious and Critical respectively) do not only NOT heal you, the spell simply refuses to acknowledge your existance. Not a single mention of any interaction, not even an Immune, in the combat log.
-----
Addendum: This may be unrelated but the character I tested it on had the Selective Channeling feat and my party members are also simply not registering on Inflict Mass spells... just like when using Channel Negative Energy - Damage Living.
-----

Here is how any other spell I could even remotely consider to fall into the negative energy damage category:
o) Harm does NOT heal you but you are Immune to the negative energy damage
o) Enervation does NOT give you 1d4 x 5 temporary hitpoints for an hour. Neither are you immune.
o) Energy Drain does NOT give you 2d4 x 5 temporary hitpoints for an hour. Neither are you immune.
o) Umbral Strike deals normal cold damage and you are immune to the negative energy damage.
o) Power Word: Kill I was unable to test due to not being able to cast it on myself and the combat log did not show any damage numbers or type when cast on an enemy. Just "You cast Power Word: Kill at target." "Target dies!" Which I find mildly amusing.
o) Destruction, even though a Necromancy spell does divine damage so it is only an honorable mention for laughs. Same with Horrid Wilting only Unholy damage.

As it is now the level 8 Death Domain power is either not working correctly (since alot of negative energy simply ignores you or damages you) ooor it should ONLY work on channeled negative energy as the power's tooltip states, but Inflict spells still do work.
Also pretty weird that single target Inflict spells work but Inflict Mass Wounds does not.

Anyway, imho it should at the very least work with Mass Inflict spells.
One could debate that you should get temporary hit-points like an undead from level drain spells, and I would argue -for- it.
Likewise if the combat log identifies the damage as Negative (as all Inflict spells do) it stands to reason you would be healed by thungs like Umbral Strike... whiiile at the same time taking damage from the cold-half of the spell. But still, gotta stay consistant, right?

Here is another honorable mention of a bug only marginally related to the issue:
Ecclisitheurge can still not use their normal spells slots to prepare domain spells. Not all of them at least.
