According to Mozilla, the 204 No Content response "indicates that a request has succeeded but that the client doesn't need to navigate away from its current page".

However, when Firefox receives such a code in response to a status code, it triggers the `window.onbeforeunload` event and any associated handlers. This has side-effects such as closing any open websocket connections associated with the page, re-rendering the DOM (which fires various lifecycle methods in single page apps), and other similar activities that are generally associated with navigating away from a page.

Is this behavior intended or documented anywhere? Or should it be considered a bug?
