Since this button works like a link, perhaps it should be highlighted
with mouse-face.

When Emacs can't display italic, it uses underline. The file faces.el
has this face spec:
(defface italic
'((((supports :slant italic))
:slant italic)
(((supports :underline t))
:underline t)
(t
;; default to italic, even it doesn't appear to be supported,
;; because in some cases the display engine will do it's own
;; workaround (to `dim' on ttys)
:slant italic))
"Basic italic font."
:group 'basic-faces)
