GravitySpace always in Global Space under user

[shiftyscales]

Describe the bug

DynamicBoneChains that are under a user will always have theri gravity calculated in global space when under a user. E.g. the hair on my avatar will shift downward further the smaller I am.

Relevant issues

None I am aware of.

To Reproduce

• Grab an object using a DynamicBoneChain with the GravitySpace set to Local Space or Parent Space
• Observe the object's gravity shifts to the same position as if it were using Global Space

Expected behavior

• The object should respect the GravitySpace regardless of whether it's under a user or not

Additional context

I had first noticed this issue as anytime I would scale my avatar down, my hair would sink into my eyes. Afterward, I investigated and discovered setting the GravitySpace should account for this, but doesn't while the DynamicBoneChain is under a user root for some reason.

This is intentional, there's a property UseUserGravityDirection that overrides the space based on the user's current gravity/space. This is so in worlds with radial or flipped gravity, the dynamic bones automatically pick it up and move appropriately.

Try unchecking this option, which should make the gravity behave the same when it's under user and when it's not.

Thanks for clarifying!
