Soul Gain Prevention Time with Vaal Skills

As of 3.4, "Vaal Soul Gain Prevention time is now modified by modifiers to skill duration and buff duration if those modifiers in some way affect the associated skill"

Many vaal skills have duration tags associated with them allowing you to stack reduced duration to get a 0 second lockout time. However there are many that do not have duration tags (Fireball, power siphon, ice nova) and for this reason have fell out of favor in the recent meta.

However, there is a nifty interaction with arcane surge support which when linked to a skill, "adds a duration component to the linked skill" and "Increases and reductions to duration will apply to the duration of the buff."

This means that using arcane surge support along with forms of reduced duration should also reduce the lockout time since this modifier to skill duration is "in some way" affecting the vaal skill by affecting a buff granted by the skill.

However, this is not the case

Both cases have ice nova at a 4 second lockout time, which is its default time.

I have also tried using items such as Timetwist and Warped Timpepiece, neither of which affect the lockout time.

It is noteworthy that immolate support holds the same affect as arcane surge support.
