I don't know, the arrangement of faces on that button is complicated,
to say the least.  I don't think I even understand which parts of the
display is the widget-field face applied to.  Can you show the
complete definition of the button face at the first line and the
non-first line?

Yes, I think we should do that.

Thanks.
