<p dir="auto">I am observing that an error thrown by a dynamic import always results in an "uncaught error".  Here is an example:</p>
<div class="highlight highlight-source-ts notranslate position-relative overflow-auto" dir="auto" data-snippet-clipboard-copy-content="// a.ts
try {
  await import('./b.ts')
} catch {
  console.log('catch')
}"><pre class="notranslate"><span class="pl-c">// a.ts</span>
<span class="pl-k">try</span> <span class="pl-kos">{</span>
  <span class="pl-k">await</span> <span class="pl-k">import</span><span class="pl-kos">(</span><span class="pl-s">'./b.ts'</span><span class="pl-kos">)</span>
<span class="pl-kos">}</span> <span class="pl-k">catch</span> <span class="pl-kos">{</span>
  <span class="pl-smi">console</span><span class="pl-kos">.</span><span class="pl-en">log</span><span class="pl-kos">(</span><span class="pl-s">'catch'</span><span class="pl-kos">)</span>
<span class="pl-kos">}</span></pre></div>
<div class="highlight highlight-source-ts notranslate position-relative overflow-auto" dir="auto" data-snippet-clipboard-copy-content="// b.ts
throw Error()"><pre class="notranslate"><span class="pl-c">// b.ts</span>
<span class="pl-k">throw</span> <span class="pl-smi">Error</span><span class="pl-kos">(</span><span class="pl-kos">)</span></pre></div>
<p dir="auto">Expected Output:</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="catch"><pre class="notranslate"><code class="notranslate">catch

<p dir="auto">Actual Output:</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="catch

<p dir="auto">There is relevant failing test in <code class="notranslate">html/webappapis/structured-clone/structured-clone.any.js</code>. We are likely not forwarding the error somewhere.</p>
