Instant loading is no restoring the page

[mercenaruss]

I have a custom part of page what include some JavaScript what is loading shopping cart.
If i open the page directly Javascript is loading and i see the cart and shopping options.
If i change page and return back to product page, shopping cart is not visible anymore .Only full page refresh is helping.

Here is minimal reproduction:

Any idea how to keep instant loading and in the same time to have shopping cart working?
