We’re trying to allow our user to embed tweets in their blog posts, but the Reply, Retweet, and Favorite icons aren’t displaying properly when we test the new page in IE7 or IE8 document mode (using IE10 developer tools). The links are there and in the correct location, but the icon image isn’t being displayed. It appears that the background image is potentially a different size, because I can get the image to show up if I adjust the background-position attribute.
Just to rule out any code on our site, I created an html page with only the embedded code and I was able to reproduce the issue.
I don’t think there is anything that we can do to resolve this on our end since the rendered tweet is contained within an iframe. Is this a known issue that might get fixed soon?
