<h1 dir="auto">Steps to reproduce</h1>
<p dir="auto">Sibling issue of <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="502974222" data-permission-text="Title is private" data-url="https://github.com/microsoft/terminal/issues/3080" data-hovercard-type="issue" data-hovercard-url="/microsoft/terminal/issues/3080/hovercard" href="https://github.com/microsoft/terminal/issues/3080">#3080</a>. Execute this:</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="echo -ne '\e[?12'; sleep 1; echo -ne '34h'"><pre class="notranslate"><code class="notranslate">echo -ne '\e[?12'; sleep 1; echo -ne '34h'
</code></pre></div>
<h1 dir="auto">Expected behavior</h1>
<p dir="auto">As if the delay wasn't there, this should attempt to enable DEC private mode 1234, which is unsupported by WT (actually undefined), so no action should be taken.</p>
<h1 dir="auto">Actual behavior</h1>
<p dir="auto"><code class="notranslate">34h</code> is printed, suggesting that parsing the sequence got interrupted.</p>
<p dir="auto">Note that if the given number is supported (e.g. 1049 to switch to the alternate screen) then the sequence is parsed and executed correctly even when a delay is injected.</p>
<hr>
<p dir="auto">Update:</p>
<p dir="auto">The same goes for unsupported CSI modes too, e.g. <code class="notranslate">\e[22;0;0t</code> (save title on stack) or <code class="notranslate">\e[4l</code> (replace mode).</p>
