CSS text-decoration:underline for <details><summary> not works in Safari

Question

Why CSS property text-decoration:underline; for <details><summary> not works in Safari?

Prefixed -webkit-text-decoration:underline; doesn’t help either.

It works in all other (include old) browsers. It works in Safari with other selectors. How make it work?

Answer 1

It is fixed as communicated here for Safari newer versions: https://bugs.webkit.org/show_bug.cgi?id=261571
