| 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. |
