title: Post comment via API to ADO Boards Work Item with hyperlink
body: <p>I am trying to create or update a work item in ADO via the API.</p>
  <p>I'd like to create a hyperlink in the comments section. I'm using the system.history field in ADO and so far I have tried the following in my payload for the field:</p>
  <ul>
  <li>URL encoding (<code>system.history=https%3A%2F%2Fgoogle.com</code>) Displays - <code>https%3A%2F%2Fgoogle.com</code></li>
  <li>Markup (<code>system.history=[google](https://google.com)</code>) Displays - <code>[google](https://google.com)</code></li>
  <li>plain text (<code>system.history=https://google.com</code>) Displays - <code>https://google.com</code></li>
  <li>HTML (<code>system.history=&lt;div&gt;&lt;a href=&quot;https://google.com&quot;&gt;google&lt;/a&gt;&lt;/div&gt;</code>) Displays nothing</li>
  </ul>
  <p>This comment field seems to support full HTML capabilities from the work item UI, can it do the same via API?</p>
