adding script in brine template breaks page scrolling

I have tried adding the below 3.js script to embed block and code block. Page scrolling stops working. Have turned off ajax page loading and parallax scrolling. Also tried per page code injection which does not show up even though saved and refreshed. Anyone have any ideas?Here is the code:
