I see the issue. and this seems like a limitation on how Facebook adds the Facebook like popup to the page.
The issue here is with the overflow:hidden from the contentWrapper.
I think if you remove that you get better resulte, however it might break other things.
Try changing <div class="wasocial_facebook_like"> to
<div class="wasocial_facebook_like" style="overflow:none !important">
Let me know if you still have the issue.
