POC tracks users with javascript disabled such as duration a tab with website is open.

Tor Browser should defend against this and probably also needs to be reported or fixed upstream to Firefox.

There are lots of ways this could be accomplished, like loading images as they come into view on a page while scrolling, or trickling bytes back to the client for a subresource. This does not strike me as a defensible barrier to try to secure.
