           Summary: Backwards text iterators occassionally missing
                    whitespaces
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Text
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: leandrogracia at chromium.org


For some input data, SimplifiedBackwardsTextIterator and BackwardsCharacterIterator seem to occasionally miss some whitespaces and put together text that shouldn't be (e.g. 'for example' -> 'forexample'). This doesn't happen if the same text is iterated forward using TextIterator or CharacterIterator and it seems to be related to m_lastTextNodeEndedWithCollapsedSpace, a functionality apparently not provided by the backwards iterators. Is this intentional as the 'Simplified' in the class name suggests?
