[css-text-decor-3] text-underline-position usage in Default UA Stylesheet doesn't match its syntax

[upsuper]

The syntax of text-underline-position is auto | [ under || [ left | right ] ] which means auto should never be combined with other values.

However, in Appendix B: Default UA Stylesheet, we have

:root:lang(ja), [lang|=ja],
:root:lang(mn), [lang|=mn],
:root:lang(ko), [lang|=ko] { text-underline-position: auto right; }
:root:lang(zh), [lang|=zh] { text-underline-position: auto left;  }

which doesn't match the syntax above.

One of them should be updated.

OK, fixed the examples to match the normative syntax, since that's what Chrome has implemented, and either way it'll be valid. Let me know if you think we should adjust the syntax definition also.
