Thai, line break only
Test passes if you see a single line with a single space before the word สากล.
Assertion: The source text [thai characters + line break + thai characters] will display as a single line with a space where the line break was.
The assumptions this test makes about expected behaviour are based on the white-space processing rules described in CSS3. The line break will be replaced by a space, because it is only removed between East Asian characters.
