When I go to the admin dashboard link for the list of Reusable blocks, performace is very slow compared to other menu items.

I’ve found that the following mysql query is run when I go to the list:
SELECT * FROM wp_posts WHERE post_content LIKE ‘%<!– wp:block {“ref”:110022}%’ and post_status IN (‘publish’, ‘draft’, ‘future’, ‘pending’)

This query does a full table scan. Can this be avoided?

The query doesn’t seem to be run for other objects, seems to be generated by the Reusable Blocks Extended plugin.
