In an article body, you can add an image.
If you do this in the final paragraph of the body field, you are unable to add further content below.

Steps to reproduce:

1. Upload an image to the Media
2. Create a new article
3. Insert an Image on the Body

The image object will be focused, the cursor will not work, and Enter key also does nothing.
The expected behavior would be the same as the Heading or Paragraph elements. Cursor and Enter key works on those cases.
