Minimum Chill/Shock not properly applying with Scolds

Character-Setup:

Cold Mastery "Chills from your hits always reduce action speed by at least 10%", Shaper of Storms "Hits always Shock, All Damage can Shock, Shocks from your hits always increase damage taken by at least 25%", and Shaper of Winter "All damage with Hits can chill" are all allocated.

Scolds Bridle is Equipped, Supreme Grandstanding from a Victario Elegant Hubris is equipped and allocated.

Bladefall of Thratus is activated in Hideout.



Expected outcome:
1) Bladefall of Thratus spends mana. WORKS.
2) Scolds hits for a small amount of physical damage every server tick. WORKS.

That should lead to various things happening:

1) I get chilled for at least 10% (because the physical damage hit from scolds can chill, and all chills from my hits chill for at least 10%, from Shaper of Winter and Cold Mastery)
2) I get shocked for at least 25% (because the same thing but for shocks from Shaper of Storms)
NEITHER OF THESE ARE HAPPENING.


3) This is unintuitive, but apparently I'm considered my own enemy for Supreme Grandstanding, so Supreme Grandstanding generates charges. THIS DOES HAPPEN.

The problem seems to not be that Scolds doesn't self-chill at all, if I'm using a higher cost (thus higher damage) skill and allocate CI for lower ailment threshold, and convert some damage taken to cold, I do get chilled - i.e. with a Flame Golem I get chilled for 8%.

However, neither the min chill (and shock), nor the "all damage with hits can chill" nor the "hits always shock, all damage with hits can shock" apply to scolds damage to shock or chill me.

I believe this to be a bug because, as proven by Supreme Grandstanding giving me charges when I'm the only character present, I am the source of the damage (as supreme grandstanding gives the source of the damage charges, and there's no ally or enemy that could share their charges with me), thus it's my damage, and my damage is guaranteed and able to chill and shock and has minimum values for both, so it should chill and shock, as secondary damage can apply ailments to me as proven by using damage taken conversion.

Conclusion:

Either Shaper of Storms, Cold Mastery and Shaper of Winter does not work as intended / has an incorrect description,
OR Supreme Grandstanding does not work as intended / has an incorrect description,
OR the secondary damage from Scolds is bugged and works inconsistently depending on effect.

Scold's Bridle self damage is considered secondary damage, so ignores offensive scaling like Shaper of Winter and Shaper of Storms minimum chill/shock.

So it's conclusion one, Shaper of Storms, Shaper of Winter and the cold mastery do not work as described, as "secondary damage" by all logical accounts is part of "all damage".

Thanks :). Still remains a bug to be fixed.

Reworking secondary damage to include offensive modifiers like the Shaper's would also mean including generic % damage scaling and all other forms of generic "all". Which also means you'd scale the self damage you take, along with giving it generic crit, and the list goes on. Which would break many existing loop builds as they have to mitigate even more damage with a scaled up self crit.

I think the more likely bug here, if any, is Supreme Grandstanding works with self damage on the helmet. The helmet is hitting you, it gains the charge, but since you're wearing the helmet you gain the charge? That logic doesn't fit to me. But maybe there's a post buried somewhere that explains it.

I'm sure they'd love to accidently suicide with Culling Strike, though.
