Thai, less than 4 common characters at line end
Test passes if you see a single line with a space before and after the number.
Assertion: The source text [thai characters + space + common characters + line break + thai characters] will display as a single line with a space before and after the common characters.
The assumptions this test makes about expected behaviour are based on the white-space processing rules described in CSS3. The common characters will be ignored during line break transformation. The line break will be converted to a space.
