title: Can Bootstrap's Tooltip be made to support both HTML and non-HTML titles?
body: <p>Bootstrap's Tooltip in general works via the <code>title</code> and <code>data-title</code> attributes of the element. I can specify HTML code via the <code>data-html="true"</code> attribute, so for example</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;a href="..." data-toggle="tooltip" data-html="true" title="&lt;b&gt;First Line:&lt;/b&gt;&lt;br&gt;Second Line."&gt;...&lt;/a&gt;
  </code></pre>
  
  <p>Which renders fine via the Tooltip plugin:</p>
  
  <p><a href="https://i.stack.imgur.com/7epSV.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7epSV.png" alt="element tooltip with JS enabled"></a></p>
  
  <p>But the problem arises when JavaScript is disabled; in this case the browser shows the raw value of the <code>title</code> attribute and in essence the raw HTML, which to the end user looks quite bad:</p>
  
  <p><a href="https://i.stack.imgur.com/jS0wq.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/jS0wq.png" alt="element title with JS disabled"></a></p>
  
  <p>Is there a way to implement graceful degradation for tooltips containing HTML? Such that an HTML-containing value will be used by the plugin, but simple, clear-text value used by default by the browser (when Bootstrap tooltips are not enabled or when JS is not enabled).</p>
