           Summary: Spatial Navigation: Crash when handling iframe of size
                    0.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: yael.aharon at nokia.com


While adding more new tests I noticed that if we have a frame of size 0, we would get into infinite loop and eventually crash.
The reason is that when the algorithm sees a starting rect of size 0, it assumes that there is no focused node, thus restarts itself.
