    [ZEPPELIN-3616] fix editor sections auto-collapse

    # Description
    This PR change logic of add new event listener on frontend. Now then add 
new event listener, also added destroy listener. Destroy listener attach to 
some DOM element and then this element destroyed listener drop event listener. 
    Since the old listeners were not deleted when changing the size of the 
paragraph / window, an error occurred. Because of this error, updating the text 
in the paragraph did not happen until the end.
