title: <input> is not clickable with Bootstrap 3 and col-md rows
body: <p>I have some "col-md-12" divs on forms that appear to "cover" preceding inputs such that they are not clickable.</p>
  
  <p>I have created a bootply with Bootstrap 3.0.0 to illustrate the issue. <a href="http://bootply.com/107074" rel="nofollow">unclickable inputs</a></p>
  
  <p>If I make the same bootply with bootstrap 3.0.3 then the input fields are now accessible <a href="http://bootply.com/107075#" rel="nofollow">clickable inputs</a></p>
  
  <p>What I want to know is whether this is a bootstrap bug that has been fixed or whether my layout is breahing some rule or other?</p>
