Ulfric's Boots can be disenchanted but Stability enchantment can't be applied to anything

[westb33]

Describe the bug

The boots of Ulfric's Boots BaseID: AADDD77 have enchantment Stability BID: A98CA5C with effect Fortify Mass can be disenchanted/learned, however the resulting known Stability enchantment can't be applied to any gear due to missing FormID for allowed targets.

To Reproduce

1. Acquire boots
2. Disenchant at enchanting table
3. With valid items to enchant and filled gem attempt to enchant, but see no valid item targets once gem and Stability are selected.

Expected behavior

Either boots should not be disenchantable/learnable via DisallowEnchanting keyword OR inclusion of FormID List for valid enchanting targets.

Additional context

I'm personally biased toward allowing the enchantment to be learned as the effect seems like a simplistic yet profound one given how it interacts with the mass system, something which otherwise can't be adjusted directly and given the prior game's usage of "feather" seems to fit well from both a lore, gameplay, balance perspective.
