Docs: .popover-inner wrapper div not present in static examples

[maniqui]

The markup of popovers on the static examples in Docs don't have a <div class="popover-inner"></div> wrapping the contents (.popover-title and .popover-content).

Example of markup (copied from docs page source) of a static popover:

     <div class="popover top">
        <div class="arrow"></div>
        <h3 class="popover-title">Popover top</h3>
        <div class="popover-content">
          <p>Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.</p>
        </div>
      </div>

Example of markup (copied from docs js-generated page DOM) of a live popover:

  <div class="popover fade right in" style="top: 2.5px; left: 242px; display: block; ">
    <div class="arrow"></div>
    <div class="popover-inner">
      <h3 class="popover-title">A Title</h3>
      <div class="popover-content">
          And here's some amazing content. It's very engaging. right?
      </div>
    </div>
  </div>

I'm not sure if the popover-inner is essential (it seems not) or old markup, or just optional markup that may allow better styling or scripting.
Some clarification on docs about it would be helpful.

It is not necessary and should have been removed. I'll update that in #6346.

Fixed in 2.3.0-wip. Thanks!
