When composing a post, the Gutenberg blocks overlap the meta boxes at the bottom of the post. I cannot enter content into those blocks so I cannot complete my post using the new editor.

All meta boxes from Advanced Custom Fields Pro are shown and the other is Yoast SEO Premium.

I presume because there is no document template option that ACF conditionals are not working so it shows all those meta boxes, but that's a separate issue.

To Reproduce
Steps to reproduce the behavior:

1. Create new post
2. Create a number of content blocks that push content to the bottom of the page
3. Gutenberg blocks and controls overlap with document meta boxes at the bottom of the page

Expected behavior
Clear separation of the content editor and the document meta boxes.

Screenshots
You can see the overlapping Title block and the eBooks and Yoast SEO meta boxes from this screenshot.
