Thai, line break only with zwsp
Test passes if you see a single line with no space before the word สากล.
Assertion: The source text [thai characters + zwsp + line break + thai characters] will display as a single line with no 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 removed, because it is next to a zwsp.
