1. Put the cursor in the middle of a paragraph
2. Insert an image
3. The inserted image is now selected, and displays an inspector button
4. Click the inspector button

It seems this happens because the post-insertion selection in step 3 covers something like </p><img></img><p> rather than just the image.
