Divi Layout block not working with Learning Mode + Yoast SEO.

[aaronfc]

Reported by Gonzalo.

Steps to Reproduce

1. Install Divi theme and enable.
2. Install YOAST SEO plugin and enable.
3. Enable Learning Mode on a Course (or full site).
4. Create a Lesson (linked to a Course with Learning Mode enabled if not enabled site wide).
5. Add the "Divi Layout" block to the Lesson.
6. Click on the "Start building" main button.

What I Expected

Divi layout builder to load correctly.

What Happened Instead

Divi layout builder stuck in loading screen.

PHP / WordPress / Sensei LMS version

WP: 6.1
Sensei Pro (WC Paid Courses): 4.8.1.1.8.1

Context / Source

• Disabling Yoast SEO plugin fixes the issue.
• Disabling Learning Mode in the Course or site fixes the issue.
• I saw some javascript errors but they do not seem related (still appear when the issue is not reproducible by not having Learning Mode enabled or Yoast SEO).
• This is preventing the usage of Divi blocks inside the Gutenberg editor. If we unblock this we make it easier for people to use Gutenberg editor more instead of Divi builder.

Thanks to @renatho we saw this is linked to this previous/known issue: #5001

Apparently adding an excerpt to the Lesson (and saving) fixes the issue.

#6342 adds a temporary solution for this. So I'm changing the priority of this issue to low. The ideal would be to investigate it further in the future and provide a better solution.
