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