He||o All  
  
I found a strange behavior of page editor.  
  
In my custom theme I have a JS on page that changes the page DOM, - adds some elements.  
  
I’ve found that those changes are saved in page template in database.  
  
This was really bad in my case - the generated by JS HTML accumulated in the page code.  
  
  
  
How could this be avoided? Is there a way to know if the page is currently edited?
