Steps to reproduce the issue

1. On a connected Jetpack Site
2. Purchase a "Jetpack Complete" plan, if the site doesn't already have one
3. Enable experimental blocks -- define( 'JETPACK_EXPERIMENTAL_BLOCKS', true ); in wp-config.php
4. Enable SEO Tools module in Calypso -- https://wordpress.com/marketing/traffic/{site}
5. Verify that you can see the "SEO description" input in the editor sidebar
6. Then activate the ActiveCampaign plugin
7. Load a post in the editor

What I expected

1. All Jetpack blocks to be available

What happened instead

1. No Jetpack blocks are available
2. There's a js error in editor-experimental.js
