Shard Scavenger not working

I tried shard scavenger shard and it seemed to not work.

Description:
While active, Consuming Freeze, Shock, Ignite, or Fully Broken Armour on an enemy reloads your Crossbow. This can only occur once every few seconds.

What I would expect is - if there is ignited minion near me - my active bolts would be reloaded without consuming mana, however during my gameplay it didn't seem to happen.

Methodology for testing:
Rapid fire - active skill - not enough mana for reload -tried both - half used magazine and fully used magazine.
Using other skills to ignite enemies (Oil Grenade and Artillery Bellista)

Result: No reloads for this scenario.

Note: Hard to 100% tests that there is no reaload with mana avaialble, but I am quite sure there has not been one

See video:https://youtu.be/75O_TwVqbvU

The video doesn't show you consuming the ignite from the burning enemy though, so no reload seems natural - there are skills that consume ailments/broken armors on the enemies they hit, and I believe some supports also add consume ignite/shock/freeze/b.armor from target to do extra X.
A good testing subject could be high velocity round, it's designed to consume broken armor to deal extra damage by itself, try testing with that?

Good point -- didn't think that it could work like that- here is longer clip with boss: https://youtu.be/WNsrzIW6zBU

As noted - didn't see any reloads also for normal skill usage - here I removed the support gems for longer fight.

Scavenger Plating as well as Shard Scavenger don't work on bosses, I checked it many times. It seems strange that in 4 months the developers couldn't fix such a simple bug.

can confirm, ran with this skill for 5 hours, not a single reload
