Ideographic, multiple line breaks
Test passes if you see a single line with no spaces after the character 行.
Assertion: The source text [ideographic characters + line break + line break + line break + ideographic characters] will display as a single line with no white space in it.
The assumptions this test makes about expected behaviour are based on the white-space processing rules described in CSS3. The line breaks should disappear since it is possible to detect ideographic characters on either side. This test checks that previous rules for line break transformation are applied for multiple linebreaks.
