Temporal Rift still is bugged and requires double the spirit of its support gems

Since original launch this bug has been in the game, if you socked a support with a spirit requirement into Temporal Rift the active component becomes unusable unless after accounting for the cost you have atleast that much spirit still free.
So if you wanna socket a Clarity 2 with 20 spirit cost into Temporal Rift you need to have 20 free spirit open permanently to be able to use Temporal Rift, effectivly doubling the spirit cost of all support gems sockete into Temporal Rift.
