layout, not DOM...

I have no idea what "if UA puts ::first-line innermost)" means, but
it seems CSS2 spec and CSS3 spec recommand different parsing:

CSS2 <http://www.w3.org/TR/REC-CSS2/selector.html#first-line-pseudo>
<p><span>blah</span></p> -> <p><p:first-line><span>blah</span></p::first-line></p>

CSS3 <http://www.w3.org/TR/css3-selectors/#first-line>
<p><span>blah</span></p> -> <p><span><p::first-line>blah</p::first-line></span></p>

Hixie,
CSS21 and CSS3 are both different. CSS21 says first-line should be outermost:

<P>
 <P:first-line>
  <SPAN class="test"> This is a somewhat long HTML paragraph that will </SPAN>
 </P:first-line>
 <SPAN class="test"> be broken into several lines.</SPAN> The first line will be
identified by a fictional tag sequence. The other lines will be treated as
ordinary lines in the paragraph.
</P>

While CSS3 specifies innermost:

<p>
 <span class="test">
  <p::first-line> This is a somewhat</p::first-line>
 </span>
 <p::first-line> long HTML paragraph that</p::first-line> will be broken into
several lines. The first line will be identified by a fictional tag sequence.
The other lines will be treated as ordinary lines in the paragraph.
</p>

The CSS21 is made 'later', but the CSS3 specification is 'newer'. Which one
should be followed?

Comment 4

[Hixie (not reading bugmail)]

CSS2.1. (CSS3 will be getting an errata at some point.)

Comment 5

This bug is INVALID (see comment 3 and comment 4).

Ian, can you fix that test case if you find time?
