Formatting issue when a picture is attached to the post

[daniloercoli]

When you attach a picture to a post/page it appears "inline" in the content box, and the caret will be positioned on the line below the picture without adding any <br/>.
So, if you hit any button in the formatting toolbar, the style will be applied also on the text before the picture.
Steps to repro:

• Write some text in the content box.
• Add a new image.
• Do not hit the 'enter' key, since the cursor is already on a new line.
• Hit the Bold button.
• Add some text, boom!
