Thai, latin next to line break
Test passes if you see a single line with a space before and after the latin characters.
Assertion: The source text [thai characters + space + latin characters + line break + thai characters] will display as a single line with a space before and after the latin characters.
The assumptions this test makes about expected behaviour are based on the white-space processing rules described in CSS3. During line break transformation, the context cannot be established as East Asian, therefore the line break is converted to a space.
