<p dir="auto">I think we need:</p>
<ol dir="auto">
<li>Create an abort controller in <code class="notranslate">page.load</code>/<code class="notranslate">pushstate</code>/<code class="notranslate">popstate</code>.</li>
<li>Pass its signal to this fetch.</li>
<li>Abort in <code class="notranslate">page.unload</code>, this will stop all currently running fetches.</li>
</ol>
