title: Why is there excessive whitespace with Facebook mobile comments plugin?
body: <p>I have been struggling with why the Facebook comments module on some of our pages have excessive whitespace on them when the pages are viewed with a mobile browser.</p>
  
  <p>After debugging for hours, I'm now singled out the specific code and it still repros.  I initially thought it was due to Twitter Bootstrap but I've compared it with and without it, and the same bug occurs.</p>
  
  <p>Compare this one that has bootstrap:
  <a href="http://jsfiddle.net/trevin/uW8fz/" rel="nofollow noreferrer">http://jsfiddle.net/trevin/uW8fz/</a></p>
  
  <p>and this one which does not:
  <a href="http://jsfiddle.net/trevin/uW8fz/" rel="nofollow noreferrer">http://jsfiddle.net/trevin/uW8fz/</a></p>
  
  <p>Both exhibit the same problem.</p>
  
  <p>If you are not signed in, you'll see like 200px of whitespace underneath. However, if you are signed in, you'll see the first comment plugin, then a huge amount of whitespace.</p>

  <p>I have no idea what's causing this.. any ideas? Is this a bug in the FB mobile comment plugin?</p>
