I took a look and tried stepping through with Edebug, but so far could
not find out how my changes in that commit cause the regression.  I
won't have time for further debugging until next week, and given my
unfamiliarty with the widget and custom code (I didn't even know about
:options till now), I may well not be able to fix this.  Feel free to
revert the commit in the mean time.  It would also be good to have a
test for this case (in emacs-30 with the commit all widget and custom
tests pass).
