r12a has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-text-decor] text-decoration-skip: spaces should not skip Mongolian NNBSP ==
2.5.1. Text Decoration Line Continuity: the text-decoration-skip property

The value `space`, when applied to the CSS property `text-decoration-skip`, breaks the line under white space. According to the [Mongolian Layout Requirements folks](https://github.com/w3c/mlreq/issues/9), there should be no break under a gap produced by the suffix separator NNBSP,  because the suffix(es) are considered to be part of the word.

The current text of the CSS spec says: "Skip all spacing, i.e. all typographic character units with the Unicode White_Space property [UAX44], plus any adjacent letter-spacing or word-spacing." This definition includes NNBSP, which is a problem for Mongolian.

There is a [test available](https://w3c.github.io/i18n-tests/run?base=css-text-decor/line-decoration&batch=line-decoration&test=text-decoration-skip-068.html), but no production browsers currently support text-decoration-skip, so there are no useful results yet, but it shows an example of relevant text.
