"Fanatism Buff" interaction with self curse temp chains and solstice vigil not working as intended.

So I wanted to do a build using the new ascendancy notables (instruments of zeal) from inquisitor that will grant "Fanatism Buff" for 4 seconds upon reaching maximum fanatism charges. So I did a quick test to see if the fanatism buff's duration expires slower with Shackles of the Wretched linked with frenzy,hextouch support, temporal chains and solstice vigil equipped. The interaction did not work with temp chains and Solstice vigil.

The picture below shows:
The Fanatism charges are affected by temp chains however the Fanatism Buff is not affected.

The frenzy charge is affected by Temp chains.
The onslaught buff is from the boot's mod which grants onslaught for 4 seconds, similar wording to fanatism's buff is also affected.
The buffs are shown with green borders around the icon. Since buffs can be affected by temp chains or solstice vigil it should be the same for the "fanatism Buff" as well.

Additional info

I am highly interested in this as well. As far as I know POEDB takes it data directly from the game so I used it to confirm that Fanatiscm is actually a Buff "IsBuffDefinition 1".
