the tool still only interacts in a real GIMP window

yep, normal sized mouse cursor, with for all the brush based
tools the brush coverage shape enlarged correctly.

it is just a temporary loupe.
what I am asking myself is 'does this thing need to be circular?
I can see the circle thing coming from a constant radius around
the mouse cursor (and a cool shape in case of the aperture loupe:

I am sure that you will feel a lot better when it can be a square,
the small and enlarged one connected by a couple of filled polygons.
