<p dir="auto">Dropdown is now collapsed by default inside responsive navbar, and required click to open. But on mobile devices, after the dropdown has been clicked open, it doesn't maintain "open" when user starts scrolling. It will automatically collapse making it not usable on mobile devices.</p>
<p dir="auto">Try open below jsfiddle result on iPhone, open the "dropdown" within menu, and starts scrolling the page. Dropdown that was opened with now close.</p>

<p dir="auto">In real life situation, when dropdown opens, it will most likely expand out of the screen. With it automatically collapse, it becomes not usable as it always collapse when scroll.</p>
<p dir="auto">I have simple dropdown buttons we built with 2.04</p>
<p dir="auto">links are A tags, proper quotes, href='#'</p>
<p dir="auto">Used to work fine.</p>
<p dir="auto">Upgraded today to 2.1 and the links in any dropdown button don't work.  The dropdown menu opens, but clicking on a link closes the menu without any action.   tested on Android 2.3 and iOS 5</p>
<p dir="auto">Rolledback to 2.04 and everything works again.  Anyone else has this issue?</p>
