Shard Scavenger + Snap

I snapped ignited enemies, with Shard Scavenger active, and they drop fire infusion, however it does not proc Shard Scavenger. My bolts did not reload and my grenades did not refresh any cd and there is no buff.
Is this intended or bug?

I have been having not too different of issues with ignite and Shard Scavenger (perhaps due to flammability rework). I know this is about a month old, but in case you have Snap in a weapon swap (specifically without a crossbow), then this combo won't work.

I got this to work with freeze, but can confirm I could not get your combo to work with ignite or shock.

Edit: It seems to work on shock/ignite against rare enemies but not magic or normal. Perhaps this is intended to balance the ailments but was undocumented in 0.3? GGG?
