Description

On a site with a lot of pullquotes on existing pages, loading posts with that content in the editor results in a block invalidation error and the paragraphs embedded in the saved content being stripped with the error "Block validation: Expected tag name 'cite', instead saw 'p'." rendered in the console.

Step-by-step reproduction instructions

1. Save some content to the DB for a pullquote block with the structure figure > blockquote > p, cite.
2. You'll receive the above block invalidation error when loading the post in the editor.
