frivoal has just labeled a pull request from frivoal for https://github.com/w3c/csswg-drafts as "Closed Accepted as Editorial":

== [css-text] Clarify handling of other space separators in white-space dfn ==
The definition of the various values of the white-space property in
section 3 does not go into much detail about exactly how they work,
and just provides a high level intro to what they do. The details are
provided in section 4, and in particular 4.1 and 4.3 (so called
“phase 1” and “phase 2” of white space processing).

While this phase 2 has been updated (see https://github.com/w3c/csswg-drafts/issues/2500, https://github.com/w3c/csswg-drafts/issues/3879, or https://github.com/w3c/csswg-drafts/issues/4180)
to define that not only space characters, but also other space
separators hang / don't hang / wrap / don't wrap, etc, based on the
value of the white-space property, the high level definition of these
values was not updated to reflect that.

While this is not necessarily a bug, as it is already called out that
details are in section 4, apparent contradictions or omissions can be
confusing.

Therefore, in the part of these definitions that explicitly talked
about white space wrapping/hanging (or not), include other space
separators as well, as defined in 4.3.
