  I am sandboxed but with "allow-scripts". I change the sandbox flags on if_18_19 to
  "allow-scripts allow-same-origin" then get it to re-navigate itself to
  file_iframe_sandbox_a_if18.html, which attemps to call a function in my parent.
  This should fail since my sandbox flags should be copied to it when the sandbox
  flags are changed.

  <iframe sandbox="allow-scripts" id="if_18_19" src="file_iframe_sandbox_a_if19.html" height="10" width="10"></iframe>
