That's fine. On the other hand, the default stylesheet rules dealing with the dir attribute (http://dev.w3.org/html5/spec/Overview.html#bidirectional-text) specify [dir] { unicode-bidi: embed; } This is fine for what used to be known as inline elements. However, as Simon Montagu recently pointed out to me, this has greater specificity than the rules for flow elements, and thus a "block" element with dir=ltr|rtl will get unicode-bidi:embed by default. This was not the intent; "block" elements should default to unicode-bidi:isolate whether they have a dir attribute or not. One way to fix that would be to add rules explicitly covering the "block" elements with a dir attribute to the four sections listed at the top of this bug. For example, instead of having address, blockquote, center, div, figure, figcaption, footer, form, header, hr, legend, listing, p, plaintext, pre, summary, xmp { display: block; unicode-bidi: isolate; } one could have address, address[dir], blockquote, blockquote[dir], center, center[dir], div, div[dir], figure, figure[dir], figcaption, figcaption[dir], footer, footer[dir], form, form[dir], header, header[dir], hr, hr[dir], legend, legend[dir], listing, listing[dir], p, p[dir], plaintext, plaintext[dir], pre, pre[dir], summary, summary[dir], xmp, xmp[dir] { display: block; unicode-bidi: isolate; } 61140 1 ian 2011-12-07 22:52:36 +0000 The problem affects more than just those elements. I should move the unicode-bidi rules all into this section to make it clearer, and then add [dir] rules to everything with 'isolate' and less specificity. 63382 2 ian 2012-01-31 01:10:05 +0000 I did it a different way in the end, but in any case the problem should be fixed now.

Check-in comment: The 'bidi-override:embed' rule for [dir] shouldn't take effect for block-level elements (since it overrides their 'isolate' rule). http://html5.org/tools/web-apps-tracker?from=6941&to=6942 63394 4 aharon.lists.lanin 2012-01-31 09:45:32 +0000 Thanks, that's great!
