missing number in text output of <ol>

[mchurch-rpc]

Describe the issue

In Section 4.6 of RFC-to-be-9599, the <ol> tag contains two <li> tags, but the "2" for the second <li> tag does not appear in the text output.

Input:

Desired output:

(which is how it looks in the HTML and PDF outputs)

Actual output (not desired):

Various workarounds have been tried by the author and the RPC without success.

Code of Conduct

• I agree to follow the IETF's Code of Conduct

HTML on Safari (both macOS and iOS) is not looking good either:

Renders correctly on Firefox and Google Chrome.
EDIT: Created #1136 for this issue.

@mchurch-rpc, As a workaround text content inside <li> can be encapsulated with a <t> tag.
For example:

<ol spacing="normal" type="1">
  <li anchor="ecnencap_reframing_goal_presence">approximate
    preservation of the presence (and therefore timing) of congestion
    marks on the L2 frames used to construct an IP packet;
  </li>
  <li anchor="ecnencap_reframing_goal_proportion">
    <ol spacing="normal" type="a">
      <li>
        <t>at high frequency of congestion marking, approximate
          preservation of the proportion of congestion marks arriving
          and departing;
        </t>
      </li>
      <li>
        <t>at low frequency of congestion marking, approximate
          preservation of the timing of congestion marks arriving and
          departing.
        </t>
      </li>
    </ol>
  </li>
</ol>

Another option is to use type="%p%c" in inner <ol>¹.

Example:

<ol spacing="normal" type="1">
  <li anchor="ecnencap_reframing_goal_presence">
    approximate preservation of the presence (and therefore timing) of congestion marks on the L2 frames used to construct an IP packet;
  </li>
  <li anchor="ecnencap_reframing_goal_proportion">
    <ol spacing="normal" type="%p%c">
      <li>
        at high frequency of congestion marking, approximate preservation of the proportion of congestion marks arriving and departing;
      </li>
      <li>
        at low frequency of congestion marking, approximate preservation of the timing of congestion marks arriving and departing.
      </li>
    </ol>
  </li>
</ol>

Output:

   1.  approximate preservation of the presence (and therefore timing)
       of congestion marks on the L2 frames used to construct an IP
       packet;

       2.a  at high frequency of congestion marking, approximate
            preservation of the proportion of congestion marks arriving
            and departing;

       2.b  at low frequency of congestion marking, approximate
            preservation of the timing of congestion marks arriving and
            departing.

Another example of this bug is

      <ol spacing="normal" type="A">
        <li>
          <ol spacing="normal" type="I">
            <li>
              Item A_I
            </li>
            <li>
              Item A_II
            </li>
          </ol>
        </li>
        <li>
          <t>Item B</t>
        </li>
      </ol>

generates:

       I.   Item A_I

       II.  Item A_II

   B.  Item B
