When scrollspy's target is set in a tab content, the tab content is forced to be invisible.
<div class="tab-content">
<div id="scroll-spy-target" class="tab-pane active">
<ul class="nav">
<li class="active">...</li>
<li>...</li>
</ul>
</div>
<div id="not-scroll-spy-target" class="tab-pane">
...
</div>
</div>
In the example, the first tab pane is not visible.
