There is an object on the next line with no attributes, inside a SPAN inside a P containing a SPAN with the 'display' style set to 'block'. It should say so. If nothing appears below this paragraph saying that the test worked, then there is a bug:

This test worked! The object is displayed Yay!

Something should be in the gap above. There should be three paragraphs on this page! (Note. A crash may occur if you select the object element, that has already been filed as bug 15018.)
