A <textarea align="right"></textarea> element causes text inside of it to be right-justified.
Instead, the contained text should be left-justified, and the align="right" should be ignored. (The align="right" should not render the whole element on the right side of the page, either.)
Firefox 188.8.131.52 and MSIE 6 both behave this way, e.g., effectively ignoring this attribute.

Note that this is not a regression as Safari v2.0.3 (417.8) on 10.4.4 behaves the same way.

Test case v2
This is a better test case. It sets the "cols" parameter large enough so you can tell which way the text was justified (right or left)!

Patch. Don't map 'align' attribute for textarea elements.
