• [x] I've read and understood the contribution guidelines.
• [x] I've searched for any related issues and avoided creating a duplicate issue.

Please give us a description of what happened.

The Yoast meta box fails to load the readability and keyword tab properly when editing posts and pages due to JS errors in the console tab, which appears to be a conflict with the plugin Gravity PDF (requires at least v1.9 of Gravity Forms installed)

Please describe what you expected to happen and why.

For the Yoast meta box to load properly when editing a post or page.

How can we reproduce this behavior?

1. Install v2.2.3.1 of Gravity Forms, v4.3.0 of Gravity PDF and v5.9.1 of Yoast SEO
2. Activate all three plugins
3. Go to any post/page and edit

Red error messages that appear in the console tab of the browser: (5)
