           Summary: <br> in <bdi> breaks paragraph around <bdi>
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: aharon at google.com

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.
