Metaboxes don't update on publish

[drov0]

When publishing on gutenberg, upon hitting publish, if you don't refresh the editor, the metaboxes won't be updated, so the "publish to steem" checkbox is still there even though the post has the "published" state.

Which means that the "update to steem" checkbox is not present and unless the editor is refreshed, the next updates won't carry over to steem.
