This is not a direct answer to your question: when we fiddle together by
hand functionality such as ossia and some things look inappropriate for
an ossia, it is tricky to call it a bug unless the visuals are
inappropriate even for the components from which we make our "ossia".
If they are just problematic because we want to call the result an ossia
stave, they are not a bug.

In order to turn such an inconvenience into a proper bug and fix it, we
need a dedicated command for creating an ossia stave.  Once we have
that, any behavior unsuitable for an ossia stave is a bug and can be
fixed.
