[Chrome] Inline Styles from contents.css added on Del or Backspace

[mandius]

Using Chrome (latest: 24.0.1312.57 m) on Windows 8 Pro 64-bit. If you hit delete or backspace at the beginning or end of a paragraph (possibly other block level elements) so that it combines the paragraphs (i.e. makes them into one) the inline styles from contents.css are added as inline styles.

For a live example, this happens at ​http://ckeditor.com/demo

• Click Source and you'll see that there are not any inline styles applied.
• Go back to WYSIWYG mode and click in front of "Apollo 11" in the first paragraph (not the heading).
• Hit backspace.
• Switch to Source mode again and inline styles have been added to the HTML.

It appears to add the BODY styles from contents.css to the elements. In this case "font-size: 13px; line-height: 1.6em;"

DUP of #9998.

Sorry, I didn't find it in the roadmap and figured it was a pretty serious bug!
