           Summary: CSS3 'word-break: break-all' spoils CJK line-break
                    restrictions
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: murakami at antenna.co.jp


CSS3 Text 'word-break: break-all' has the following definition:

‘break-all’
  In addition to ‘normal’ soft wrap opportunities, lines may break 
  between any two letters (except where forbidden by the ‘line-break’ 
  property). Hyphenation is not applied. This option is used mostly 
  in a context where the text is predominantly using CJK characters 
  with few non-CJK excerpts and it is desired that the text be better 
  distributed on each line. 

However, in the current WebKit implementation, 'word-break: break-all'
does not only allow line-break between non-CJK letters but also 
spoils any line-break restrictions, e.g., opening brackets at end of
line, and closing brackets or comma/fullstops at beginning of line.
