           Summary: insertAdjacentHTML raises RangeException (possibly
                    caused by node with no parent)
           Product: konqueror
           Version: 4.2.1
          Platform: Ubuntu Packages
        OS/Version: unspecified
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: khtml
        AssignedTo: konq-bugs@kde.org
        ReportedBy: kde@metafoo.co.uk


Version:            (using KDE 4.2.1)
Installed from:    Ubuntu Packages

The following javascript causes Konqueror to hit a RangeException, but it works
in IE:

  document.createElement("div").insertAdjacentHTML("beforeEnd",
"<span>foo</span>")

The problem appears to be caused by the usage of range.setStartBefore(node) in
the implementation of insertAdjacentHTML -- this fails with RangeException if
the node has no parent. The draft HTML5 spec requires insertAdjacentHTML to be
a (non-throwing) no-op for a parentless node if in "beforeBegin" or "afterEnd"
mode, and to operate normally in the other two modes for a parentless node:
