Yea, a couple of things. I contacted Cloudflare about this.
It does indeed seem to be from their end. Cloudflare also seems to cache / minify JS CSS etc on a WordPress users admin panel.
They stated that they were working on a fix to this for their next update.
It's something that pokes it's head up every now and then. Rather than disable anything, I found that if something comes up, I simply empty the cloudflare cache from their site admin (not any WP cache if running a caching plugin) and the situation is immediately resolved.
