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." />

Key to entities used below:
‎ - LRM, the invisible left-to-right mark (strongly LTR).
‏ - RLM, the invisible right-to-left mark (strongly RTL).
This test makes sure that the direction is set correctly for a textarea whose value is set
dynamically by script.
We use text-align:left because neither the dir="auto" nor the unicode-bidi:plaintext
specification states whether text-align:start and text-align:end should obey the paragraph
direction or the direction property in a unicode-bidi:plaintext element.
