Only workaround is to put something else, like maybe a flower or a shelf, ontop of that chain in the second floor.
That is if you dont want to have the chandelier hanging lower, which would actually look nicer and also more realistic in my opinion.
If I hang it lower it will touch the ground, LOL!
ZOS should just add chandelier versions (same) with shorter chain. That would fix the problem imho.

Take a screenshot of your character standing under it?
There's the chair in the screenshot for comparision.
My character won't touch the chandelier but it will be close.
Chandeliers are supposed to hang higher, not about to touch human heads or just a one or two meters above chairs.
