I looked at it and off the bat, I can't see anything that looks janky, but then that was a lot of page cache there so I may have missed something. I can forward it to our dev team to take a look at if you want. I think its just a cached page and is most likely being flagged because of the base64 and eval statements it contains. We had another sample sent to us from a user with w3tc enabled and it looked much the same. We're actually looking into giving users the ability to exclude directories from scans to avoid this sort of thing.
Let me know what you would like to do.
