<p>Otherwise, <var>result</var> is a <span>module script</span>. <span data-x="fetch the

descendants of a module script">Fetch the descendants</span> of <var>result</var> given

<var>destination</var> and an ancestor list obtained by appending <var>url</var> to <var>ancestor

list</var>. Wait for <span data-x="fetch the descendants of a module script">fetching the

descendants of a module script</span> to asynchronously complete with <var>descendants

result</var> before proceeding to the next step.</p>

<p class="note">If the asynchronous completion result is null, meaning that fetching one of the

descendants failed, we still proceed through the next set of steps. A failure will shortly occur

during instantiation, which we then react to appropriately. The error signal is eventually

propagated to the caller of this algorithm in the last step.</p>

<li><p>Assert: <var>s</var> is a <span>module script</span> (i.e., it is not

fetched).</p></li>
