<p dir="auto">If a navbar dropdown is left open during collapsed (mobile) mode, then resized to horizontal (desktop) mode, it wont work straight.</p>
<p dir="auto"><a href="http://getbootstrap.com/examples/navbar/" rel="nofollow">http://getbootstrap.com/examples/navbar/</a></p>
<p dir="auto">Maybe the navbar should auto-close all dropdowns on collapsed mode to horizontal mode switch.</p>
<p dir="auto">Steps to reproduce:<br>
Open, for example, bootstrap-3.0.2\examples\theme\index.html.</p>
<ol dir="auto">
<li>Make screen smaller to get collapsed nav bar</li>
<li>Click on one of menu for drop-down list in nav bar</li>
<li>Maximize screen again</li>
<li>Go to Drop-down - drop-down and click again -  list will be in scroll area.</li>
</ol>
<p dir="auto">Did the same on tablet Nexus - 7'' : Landscape and Portrait, the same effect. After refresh everything is fine again.</p>
