title: Facebook Share Button is ignoring og:meta tags
body: <p>I have tried using the direct link to sharer.php but with the problems managing the popup window and closing it, and the fact that Facebook gives no documentation on it with the real parameters (ie p[title], etc.), it seems imprudent to rely on that method.</p>
  
  <p>So I am following the instructions given by Facebook, and it doesn't pick up any of the meta properties they have defined. I have copied the syntax directly, it is placed properly in the head of the HTML document, and that entire HTML document is in an iFrame to prevent any outside interaction.  The Share window pops up as expected, but none of the properties (save the url included in the a tag) are populated.</p>
  
  <p>Ironically, when I navigate directly to that page in my browser, and instead, click on the Share on Facebook bookmarklet, it DOES correctly read the meta properties!</p>
  
  <p>Any suggestions would be appreciated, unless they are, "use the like button", because it's not at all the same.</p>
