Assertion: The source text [ideographic characters + 10 common characters + line break + ideographic characters] will display as a single line with a space after the common characters.

Notes:
The assumptions this test makes about expected behaviour are based on the white-space processing rules described in CSS3. There are more than 4 common characters on one side, so the implementation may not ignore them when establishing the context. Since the context is ideographic, the line break will be removed.
