Trigger gem "missing socketed skill" when socketed skill is set to weapon set 2 only

Bug report # 2,853,410,796.

Steps to reproduce:
- Place Voltaic Mark on skill bar
- Set Voltaic Mark to weapon set 2 only
- Move Voltaic Mark to Cast on Freeze socket
- Cast on Freeze shows "Missing socketed skill" and cannot be enabled

Recovery:
- Move Voltaic Mark back to skill bar
- Set Voltaic Mark to weapon sets 1 and 2
- Move Voltaic Mark to Cast on Freeze socket
- Cast on Freeze can now be enabled

Switching weapon sets does not make Cast on Freeze enable-able.

It appears that which weapon sets a skill are enabled from is stored in the gem itself, probably for consistent behavior. However, this is not overridden when socketed in trigger gems.
