In reply to Zeb.

It's a bug in Yoast, caused by the Gutenberg team removing a dependency in a release that only got a single day of pre-release testing.

Although Yoast made a mistake by not registering the enqueues themselves, I'm not sure how any third party developer could be expected to test and release fixes with such a short beta period.

Gutenberg has 300k+ users now and is advertised in core. It needs to start treating releases like a real core feature would, and give adequate time for the dev community to test beta releases.
