1. Place a Blogs portlet on a page and start adding a new blog.
2. Type something in the title field.
3. Expand the Configuration section and select the Custom Abstract radio button.
4. Type something in the field.
5. Start typing something in the Content field.
Result: The text typed in at step 4 for Custom Anstract disappears.
Expected: It should not disappear, unless this is intended for some reason.
