The HTML5 spec (http://dev.w3.org/html5/spec/Overview.html#the-bdi-element) states that "For the purposes of applying the bidirectional algorithm to the paragraph-level container that a bdi element finds itself within, the bdi element must be treated like a U+FFFC OBJECT REPLACEMENT CHARACTER", i.e. as a neutral character. Thus, a <bdi> containing a <br> (which serves as a paragraph break in the content of the <bdi>) must *not* serve as a paragraph break in the content around the BDI (since a neutral character does not do so). Unfortunately, currently, the content before and after a <bdi> containing a <br> is rendered as separate bidi paragraphs, and so directional runs and other bidi effects that would otherwise be formed between the two are severed.

The CSS spec may be changed in this respect due to a recent proposal to add isolates to Unicode and to make the CSS feature make use of the new Unicode feature - which will require changes to the details of the CSS spec. Details at http://lists.w3.org/Archives/Public/public-i18n-bidi/2012AprJun/0022.html

The CSS spec has indeed been changed, and this behavior is now according to spec.
