textarea with dir=auto, script assigns to all-N between all-Rs
Test passes if the two boxes below look exactly the same.
Assertion: When dir='auto', the direction is set according to the first strong character of the text. For textarea and pre elements, the heuristic is applied on a per-paragraph level. If there is no strong character, as in this test, the direction defaults to LTR.
