title: Facebook Comments: capthca doesn't fit
body: <p>I have added Facebook comments to my site as it is described in official guide:</p>
  
  <p><a href="https://developers.facebook.com/docs/plugins/comments#configurator" rel="nofollow noreferrer">https://developers.facebook.com/docs/plugins/comments#configurator</a></p>
  
  <p>But when I try to post something captcha appears, and since the iframe is too short, it does not fit at height, so I see only the lowest part and don't see the top part, so I can't solve the captcha and post the comment.</p>
  
  <p>If I try to increase height if the iframe with Chrome debugger then I see full captcha overlay and can solve it and then my post is added. But regular visitors of the site, of course will not debut it with debugger.</p>
  
  <p>Is there a way to solve this? iframe's height is hardcoded with style attribute, so, I guess it's not solved with just css...</p>
