Prevent Web Application Designer from Replacing Quotes

I have a piece of JavaScript that I use to hide some error display that's not important right now. The problem is if I or someone else makes changes to the web app and saves the Web App Designer will replace the quotes with the HTML encoded quote and it breaks it. Is this something I can turn off?

<script type="text/javascript" >document.getElementById("__MESSAGES_LIST_ITEM_AcMess_scl").style.display = 'none';</script>
