Disabling Page Scroll when Cursor is Over Div (Chatango) - html

Question

I'm adding a Chatango HTML5 chat box to my website, but when users scroll up or down in the chat box, it also scrolls up or down the rest of the page. I've been experimenting with different codes I've found on this site, but so far nothing has worked.
I thought I found a solution here: How to disable scrolling in outer elements? and applied it to my chatroom. It works exactly how I want it to on this codepen editor: http://codepen.io/EagleJow/pen/QbOBJV
But using the same code in JSFiddle: https://jsfiddle.net/4bm6ou90/1/ (or on my actual website) does not prevent the rest of the page from scrolling. I've tested it in both Firefox and Chrome with the same results.
Here's the javascript:
var panel = $(".panel");
var doc = $(document);
var currentScroll;
function resetScroll(){
doc.scrollTop(currentScroll);
}
function stopDocScroll(){
currentScroll = doc.scrollTop();
doc.on('scroll', resetScroll);
}
function releaseDocScroll(){
doc.off('scroll', resetScroll);
}
panel.on('mouseenter', function(){
stopDocScroll();
})
panel.on('mouseleave', function(){
releaseDocScroll();
})
Any ideas?

It didn't work on JSFiddle because I didn't have jQuery set on the side menu and it didn't work on my website because the '$' symbol in the javascript conflicted with that same symbol in the jQuery (or something like that).
Here's the JSFiddle with better code and set to load jQuery: https://jsfiddle.net/4bm6ou90/7/
The Javascript:
$.noConflict();
jQuery( document ).ready(function( $ ) {
$(".panel").on("mouseenter", function(){
$(document).on("scroll", function(){
$(this).scrollTop(0);
});
});
$(".panel").on("mouseleave", function(){
$(document).off("scroll");
});
});
Also gotta have that jQuery CDN in the html head section.
