Aura disappears when token is on GM layer

I'm not sure if this is working as intended, but I have a token that's hidden on the GM layer, but while it's there, the aura that I set does not show up. As soon as I move it to the token layer, it's there. (Not player visible, just DM visible in either case)

It doesn't actually bother me, since I don't need the aura until the monster reveals itself. I just was a little confused at first because I set the aura while it was on the layer, and then nothing happened. The closest thing I could make to an argument is if I was using a hidden object with an aura to diagram a trap or something, but in those cases I just make the token bigger, so I got nothing. :)

I *can* think of many use cases for an aura on the GM layer, but I think having the full aura could be a visual clutter. Maybe just paint the border of the aura as dotted line?

Invisible monster that has an AOE/Aura would be one easy use case.

Maybe just paint the border of the aura as dotted line? I would actually love to see that as an feature on the object layer as well. :) Especially if we can change the colors of the dotted line.
