Describe the Bug

I added a collapsible block with a code block inside. When I save the page and go back to edit, I see nothing in the editor. I'm using the new WYSIWYG. I have tested this multiple times in other books, and the same thing happened.

Steps to Reproduce

Create a new page
Add Title
Add Collapsible Block
Expand Collapsible Block
Add Code Block
Save Code Block
Save Page
Edit Page

Expected Behaviour

You should be able to add a code block to a collapsible block and then edit the page in the future.
