Global Posts Feed is outputting raw text instead of formatted HTML

I have installed the Recent Global Posts Feed plugin, but it is not rendering the posts' HTML correctly.

Please compare the following:

* http://ourlittlegreendot.com/wp-content/recent-global-posts-feed.php?posttype=post
* http://ourlittlegreendot.com/feed/

If you search for "We just wrapped up" in each feed you'll see that the normal feed is wrapped correctly with p tags, and other Wordpress formatting, but the Global Posts Feed just has the raw text.

The post content should be filtered before being output to the feed. Is there an option to enable this, or an updated plugin where this is implemented?
