[anchor] Don't scope inline container anchor references.

Previously we'd scope anchor references to those contained by the
inline container. However this is incorrect, and instead should allow
everything at the containing-block level.

For example:

\<div id="a" style="position: static;">
\<span style="position: relative;">
\<div id="b" style="position: absolute; anchor-name: --b">\</div>
\</span>
\<span style="position: relative;">
\<div id="c" style="position: absolute; top: anchor(--b top);">\</div>
\</span>
\</div>

In the above example the containing-block is "a". Previously "c"
couldn't anchor to "b", however upon discussion with Tab we should
allow this.
