  Problem Summary:
  
  When the cleanup mechanism tries remove the context used to
  execute JavaScript,
  the cleanup fails, because the current context does not belong
  to the function
  that needs to be cleaned up.
  

Problem conclusion

• The fix ensures, that the cleanup takes place when the
  JavaScript was executed
  and the context can be disposed.
