CONSOLE ERROR: line 1: Uncaught SecurityError: Sandbox access violation: Blocked a frame at "null" from accessing a frame at "".  The frame requesting access is sandboxed and lacks the "allow-same-origin" flag.
This test verifies that a sandboxed IFrame cannot access the history object of the top-level frame. It passes if an uncaught exception is present, noting that the inner frame cannot access the outer.
