Comment (by aduth):

 Still seeing this happen as of today, August 3, 2018.

 I [https://wordpress.slack.com/archives/C02QB8GMM/p1533313819000122
 commented in Slack] with a suspected cause.

 >The white screen is caused by this line:
 https://meta.trac.wordpress.org/browser/sites/trunk/wordpress.org/public_html
 /wp-content/themes/pub/gutenberg/functions.php?rev=7584#L158
 >Probably a race condition with the initialization of the editor, which is
 slightly more involved
 https://github.com/WordPress/gutenberg/blob/9ae5aa223ef80c48f2352e4b90ffaefc37bc5258/lib
 /client-assets.php#L1292-L1298
 >Instead of `wp.domReady`, it should probably be using
 `window._wpLoadGutenbergEditor.then`
