Description Aharon (Vladimir) Lanin 2011-10-30 10:34:27 PDT
unicode-bidi:-webkit-plaintext is supposed to be on by default for <textarea dir=auto>. However, currently (at least in Chrome 15.0.874.106 and 17.0.919.0), it is also on by default for <textarea dir=ltr> and <textarea dir=rtl>. This breaks backwards compatibility.

test case: data:text/html,<textarea dir=rtl>the period should be on the left.</textarea>

According to the HTML spec (http://dev.w3.org/html5/spec/Overview.html#bidirectional-text), the correct default stylesheet as relating to unicode-bidi is supposed to be:

[dir] { unicode-bidi: embed; }
bdi, bdi[dir], output, output[dir], [dir=auto i] { unicode-bidi: isolate; }
bdo, bdo[dir] { unicode-bidi: bidi-override; }
bdo[dir=auto i] { unicode-bidi: bidi-override isolate; }
textarea[dir=auto i], pre[dir=auto i] { unicode-bidi: plaintext; }

Also see https://bugs.webkit.org/show_bug.cgi?id=70373 for another bug due to an incorrect default being set for unicode-bidi.

Kudos to Amir Aharoni on finding this bug.
