Thrilling Chase does not proc for Charge Infusion

The Deadeye ascendency skill "Thrilling Chase" is supposed to double the benefits from consuming Frenzy Charges (50% of the time) for your skills.

The skill "Charge Infusion" consumes a Frenzy Charge every 4.3 seconds to maintain a buff that grants 8% more skill speed.

Based on this logic, Thrilling Chase should double the benefit of Charge Infusion, granting 16% more skill speed buff (50% of the time). However, this isn't happening and Charge Infusion grants the same exact buff with or without Thrilling Chase all the time while my Frenzy Charges are being consumed.

I don't believe this is a bug as per the description of the skill. Charge Infusion does not consume charges to give a buff, it just gives a buff while you have charges and happens to consume charges every so often.
