[csswg-drafts] Issue: [css-text-decor-3] behavior of text-decoration + text-emphasis marked as i18n

r12a has just labeled an issue for https://github.com/w3c/csswg-drafts
 as "i18n":

== [css-text-decor-3] behavior of text-decoration + text-emphasis ==
I think that the spec mentions behavior of text-emphasis + ruby (see 
below) but doesn't say behavior of combination of text-decoration and 
text-emphasis.

> If emphasis marks are applied to characters for which ruby is drawn 
in the same position as the emphasis mark, the emphasis marks are 
placed outside the ruby. 
https://drafts.csswg.org/css-text-decor-3/#text-emphasis-position-property

>From an aesthetic point of view, text-decoration and text-emphasis 
should be separated from each other.

Furthermore, I feel that we have to think more complex pattern such as
 mixing text-decoration, text-emphasis and ruby.
