/**
 * Makes dismissing the review notice stick.
 *
 * WordPress draws the cross on any notice carrying "is-dismissible", but all
 * it does is remove the element -- the next page load brings it straight back.
 * Everything here is therefore an enhancement of something that already works
 * without it: "No thanks" is a real link to a real handler, and following it
 * records the refusal and returns to the page. This just spares the reload,
 * and gives the cross the same meaning as the link next to it.
 *
 * No build step and no dependencies. The URL and its nonce arrive in a data
 * attribute rather than in an inline script, which is the same reason the
 * front end carries data-cx: a page with a strict Content-Security-Policy
 * should not need an exception on this plugin's account.
