Converting rich text copied from VS code results in bad markdown

[FezVrasta]

When I copy the following code from VS code and read it from the clipboard I get this HTML:

<meta charset="utf-8" />
<div
  style="
    color: #d8e2ec;
    background-color: #171d23;
    font-family: 'Fira Code', Menlo, Monaco, 'Courier New', monospace, Menlo,
      Monaco, 'Courier New', monospace;
    font-weight: normal;
    font-size: 13px;
    line-height: 20px;
    white-space: pre;
  "
>
  <div>
    <span style="color: #9d7cd8; font-style: italic">const</span
    ><span style="color: #d8e2ec"> </span
    ><span style="color: #bb9af7">turndownService</span
    ><span style="color: #d8e2ec"> </span><span style="color: #89ddff">=</span
    ><span style="color: #d8e2ec"> </span><span style="color: #89ddff">new</span
    ><span style="color: #d8e2ec"> </span
    ><span style="color: #7aa2f7">TurndownService</span
    ><span style="color: #9abdf5">()</span><span style="color: #89ddff">;</span>
  </div>
  <div>
    <span style="color: #c0f0f5">turndownService</span
    ><span style="color: #89ddff">.</span><span style="color: #7aa2f7">use</span
    ><span style="color: #9abdf5">(</span><span style="color: #c0f0f5">gfm</span
    ><span style="color: #9abdf5">)</span><span style="color: #89ddff">;</span>
  </div>
  <br />
</div>

The resulting markdown is:

  

const turndownService = new TurndownService();

turndownService.use(gfm);

I would expect it to result in:

const turndownService = new TurndownService();
turndownService.use(gfm);
