Change subject: Pre-fetch RESTBase DNS and negotiate TLS
......................................................................
Pre-fetch RESTBase DNS and negotiate TLS
Keep VisualEditor load times snappy by eagerly establishing a connection with
RESTBase via a beacon request, which is deferred until after window.onload /
setTimeout to ensure it does not slow down the loading of the page.
