[css-flexbox] Prose about white space characters links to the white-space property

However, if the entire sequence of child text runs contains only white space (i.e. characters that can be affected by the white-space property) it is instead not rendered (just as if its text nodes were display:none).

The first link is to https://www.w3.org/TR/CSS2/text.html#white-space-prop which is for the white-space property in CSS2. It doesn’t (directly) define a set of characters. Should this link go to https://drafts.csswg.org/css-text/#white-space instead?

@SimonSapin Yes. Done. (I suspect css-text-3 wasn't mature enough to use as a reference when this was drafted up.)
