PHP Notice: jetpack/modules/custom-css/custom-css-4.7.php:153 - Undefined index: post_type

[pento]

I'm not entirely sure how to reproduce this notice, I think it's to do with when a post draft is saved by clicking the "Save Draft" button. But, it's showing up in the error logs, so I'm reporting it here. :-)

The optional $post argument for _wp_post_revision_fields() was added in 4.5. While core passes the $post argument plugins like Email Post Changes do not. https://plugins.trac.wordpress.org/browser/email-post-changes/trunk/class.email-post-changes.php?rev=1214233#L102

This is causing a mess of the error logs on w.org, so I'm moving this to the next point release.
