We have a Zemanta plugin (PRO account) for WordPress 3.5.2. We recently upgraded the plugin from 1.1.2 to 1.2.2, and noticed the image-settings, have and issue with the default WP's media editor.
On a new post, when a new image is inserted from Zemanta and immediately open the image edit modal (from view tab, clicking the "edit image") and trying to update the caption, the caption won't be updated.
Please keep in mind that since on image click, it opens up the image settings for the inserted image, and double click will open the media modal.
However, we noticed that once the post is saved, or if I switch to a text tab and back to view tab, I can update the caption through media editor.
Is this a glitch or known issue that would be fixed on the future release?
