I think underline text decorations should always extend over annotations 
for |ruby-align: center|. I ran into this issue in Firefox 50 recently 
where a link was split into two to three components because of the "ruby 
overhang skip" effect and ultimately decided to hide all annotations 
nested within annotations because the presentation was so ugly.

I can imagine desirability for ruby underlines not extending over a 
final overhang for |ruby-align: start| or empty bases at either end of a 
ruby sequence, but I don't think it would be terrible for underlines to 
extend over those annotations either.

I've posted some (real world) ruby examples of the text I was working 
with at
