The delay is css based not js based, so why would blocking all js affect it?

If you tell the browser to disable execution of all <script> tags, it will instead evaluate the <noscript> tag which contains some additional CSS that disables the animation.

Ah, I didn't realise/remember it has a noscript block, it's been a while since I dug into the issue originally.
