title: Facebook share description missing
body: <p>I am using the Facebook debugger to check the scraping of my page but the description is always missing.</p>
  
  <p>You can go here <a href="https://developers.facebook.com/tools/debug/og/object/" rel="nofollow noreferrer">https://developers.facebook.com/tools/debug/og/object/</a>  and input my page's url <a href="http://on.aol.com/video/kit-harington-teases-possible-return-to-got-519083276" rel="nofollow noreferrer">http://on.aol.com/video/kit-harington-teases-possible-return-to-got-519083276</a>    And click "fetch new scrap information".</p>
  
  <p>You will see that this page has all expected Open Graph tags and the preview looks like this: 
  <a href="https://i.stack.imgur.com/HSS72.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/HSS72.png" alt="enter image description here"></a></p>
  
  <p>But problem is coming!!! When you click the image or the "See this in the share dialog" to open the real share dialog, the description is missing like this:
  <a href="https://i.stack.imgur.com/woH2O.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/woH2O.png" alt="enter image description here"></a></p>
  
  <p>I am the admin of the Facebook app for this page so "fetch new scrap information" should have refreshed the cache of this page. But when you click "Fetch existing scrape information", description always missing as well.</p>
  
  <p>For more info, you can directly check <a href="http://on.aol.com/video/kit-harington-teases-possible-return-to-got-519083276" rel="nofollow noreferrer">http://on.aol.com/video/kit-harington-teases-possible-return-to-got-519083276</a> or any other video page in <a href="http://on.aol.com" rel="nofollow noreferrer">http://on.aol.com</a> and click the "Facebook" share button on the left to see it. It would look like below and description still missing!
