Increases to cast speed do not properly scale the triggered cooldown of Lightning Conduit

What is the expected behaviour/value?

Increases/reductions to cast speed should scale the cooldown of Lightning Conduit when triggered. This can be tested by linking Faster Casting Support to Lightning Conduit in game and looking at the tooltip cooldown.

What is the actual behaviour/value?

Path of Building only scales the cooldown of a triggered Lightning Conduit through cooldown recovery rate, and not cast speed as expected.

How to reproduce the issue

1. Select Lightning Conduit as a main skill and link it to CoC
2. Note the "Final Cooldown of Trigger" under Trigger Rate Cap (Calcs Screen)
3. Add Faster Casting Support to the gem setup
4. Note the trigger cooldown again

Reproduce the issue with Lightning Conduit linked to CoC, first noting the Final Cooldown of Trigger in the Calcs Screen, then adding Faster Casting Support and comparing the value. Trace the calculation that produces the trigger cooldown and check where cast speed and cooldown recovery rate are applied. Done means the cooldown changes with Faster Casting Support as it does in game.
