Drop down in nav bar misbehavior in mobile

[OscarHYCheung]

The drop down items in navigation bar is not working in mobile device anymore after upgrading to v2.3.2.
The drop down list will be closed instead of going to corresponding hyperlink when clicking the children items on mobile.

<div class="navbar">
  <div class="navbar-inner">
    <div class="container">
      <a class="btn btn-navbar" data-toggle="collapse" data-target=".navbar-responsive-collapse">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </a>
      <a class="brand" href="#">Title</a>
      <div class="nav-collapse collapse navbar-responsive-collapse">
        <ul class="nav">
          <li class="active"><a href="#">Home</a></li>
          <li><a href="#">Link</a></li>
          <li><a href="#">Link</a></li>
          <li class="dropdown">
            <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
            <ul class="dropdown-menu">
              <li><a href="http://www.google.com">Action</a></li>
              <li><a href="http://www.google.com">Another action</a></li>
              <li><a href="http://www.google.com">Something else here</a></li>
              <li class="divider"></li>
              <li class="nav-header">Nav header</li>
              <li><a href="http://www.google.com">Separated link</a></li>
              <li><a href="http://www.google.com">One more separated link</a></li>
            </ul>
          </li>
        </ul>
      </div><!-- /.nav-collapse -->
    </div>
  </div><!-- /navbar-inner -->
</div>

The upper code should generate a nav bar.
When you click on children of "Dropdown",
it will bring you to Google.
But it is not working on mobile.
