           Summary: dir=auto should imply unicode-bidi:isolate by default
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: aharon at google.com


Per http://dev.w3.org/html5/spec/Overview.html#bidirectional-text, the default style sheet should say, among other things:

bdi, output, [dir=auto] { unicode-bidi: isolate; } /* case-insensitive */
bdo, bdo[dir] { unicode-bidi: bidi-override; }
bdo[dir=auto] { unicode-bidi: bidi-override isolate; } /* case-insensitive */

I.e. dir=auto implies unicode-bidi:isolate by default. Other dir values, e.g. dir=ltr, should continue to imply unicode-bidi:embed.
