Glacial Hammer visual effect incorrectly offset for 2H cosmetic weapons

As title says, the visual ice effect when Glacial Hammer is used is offset on ALL 2-handed weapon cosmetics I've tried (this bug is not limited to the Silver Crescent cosmetic). The offset seems to be at the position where the non-cosmetic weapon head would have been, instead of where the cosmetic's weapon head actually is. I have not tested this with one-handed weapons.

I've posted two screenshots to illustrate.

Glacial Hammer effect bug with 2H Silver Crescent skin. Note the weapon's head position being higher on this cosmetic than the effect:


Glacial Hammer effect bug with no cosmetic. Note the weapon's head position being in line with the effect:

Bump. Is this known?
