[css-lists] Error in example 19 in the Lists spec

[jfkthame]

See "Example 19" at https://drafts.csswg.org/css-lists/#list-item-counter. The example markup shown is

<ol>
  <li>First top-level item
  <li value=5>Second top-level item, value=5
    <ol start=3>
      <li>First second-level item, list start=3
      <li>Second second-level item, list start=3
        <ol reversed>
          <li>First third-level item in reversed list
          <li>Second third-level item in reversed list
          <li>Third third-level item in reversed list
          <li>Fourth third-level item in reversed list
        </ol>
    </ol>
  <li>Third second-level item, list start=3
  <li>Third top-level item
</ol>

but I believe the intention is clearly for the "Third second-level item" to be before, not after, the second of the three closing </ol> tags. Otherwise it becomes a "top-level item" instead.

In addition, it seems "Example 22" at https://drafts.csswg.org/css-lists/#counter-functions is also incorrect: its use of counter-reset on the heading elements without a proper nesting structure of document sections, subsections, etc. means that it will not render as expected in a spec-conformant browser. See comments 8 and 9 at https://bugzilla.mozilla.org/show_bug.cgi?id=1718070.

As @MatsPalmgren notes in https://bugzilla.mozilla.org/show_bug.cgi?id=1718070#c9, it should probably be amended to use counter-set instead.
