You are right.

I thought (slippery memory) that the fringe bitmaps were still
determined internally even if the fringes have zero width, but they
are not.

However, it would be trivial to add a new variable force-fringe-bitmap-update
or some such which did the fringe calculations even for zero-width fringes.
WDYT?
