Lightning Bolt from Foulborn Mjolner - unaffected by Cooldown Recovery Support

After a bit of testing, it seems the new support does not have any effect on Lightning Bolt's cooldown. It alone should hit the 27%+ breakpoint, but with a .2 - .22 attack speed cyclone it only triggers every other hit. Going back up to .25 attack speed triggers per-hit again.

I'm unsure whether this is a problem with Lightning Bolt itself being (un)affected by CDR or just the support - more testing required. Also unsure whether Choir of the Storm's bolt behaves similarly.

Would love to know if this is a bug or the intended behavior for foulborn mjolner. It seems to be also unaffected by Saboteur's "Like Clockwork" passive (50% increased Cooldown Recovery Rate). I really hope the cooldown becomes scalable as this item is pretty unusable in it's current state.

It does appear that certain global sources of CDR apply. Increased CDR on eldritch boot implicit + Bound by Destiny's "increased Cooldown Recovery Rate if 2 Shaper Items are Equipped" can visibly hit the 27% breakpoint via the same test in my original post.

If it's true that Like Clockwork does not apply like mentioned above, there's definitely some inconsistency and buggyness around its cooldown.
