Assertion: The source text [thai characters + spaces + line break + spaces + thai characters] will display as a single line with a single space where the line break was.

Notes:
The assumptions this test makes about expected behaviour are based on the white-space processing rules described in CSS3. The white space on the second line is removed in the first step of the white-space processing rules. The spaces at line end are not removed before line break transformation (LBT). Line break transformation then converts the line break to a space. Spaces are then normalized to one space.
