Why is that?
Because constructable stylesheets are only implemented in chrome at the moment. They're on the roadmap.

Hi :) is there any ETA? Thanks!
We haven't yet started to work on this feature, so no ETA yet.
But as I said in bug 1520690 I'm happy to mentor people to prototype this if there's somebody interested.
