Decaying Hex and Support Gems

Currently on live when you socket Decaying Hex into a curse and then further socket support gems, which should apply to Decay, they do nothing.

The Decay debuff does not have its damaged increased or decreased, and the duration of the debuff does not change as excepted. No change happens at all. Some of these supports, such as damage increasing supports, can only be socketed into the curses after you have socketed Decaying Hex, which implies they are intended to work together.

The very similar support gem, Corrupting Cry, IS altered by support gems as expected. This implies the support gems are not disabled purposefully for Decaying Hex.

Additionally the Decay debuff duration is not altered by the character stat Skill Effect Duration from the passive tree. I'm not sure if that is intended.

There is no noted change to Decaying Hex in the 0.3.0 Patch Notes.

This bug has persisted for 9 months. Please Please find time to address it for 0.3.0 patch.

I would really like to play a decaying hex build...

Oh I just noticed. These Decaying Hex bugs have persisted for so long they are now noted in the main skill functions section of the Decaying Hex skill on the wiki. Which also notes that they are probably an unaddressed bug.
