Comment (by michelleeby):

 == Steps to test

 1. Using 2 different wp-env environments, create an environment for the
 patched version of WordPress and another for "vanilla" WordPress Core.
 Then continue to follow the steps for both.
 2. Install and activate data-wp-each-test plugin, which is attached to
 this ticket as a zip.
 3. Install and activate Query Monitor, https://wordpress.org/plugins
 /query-monitor/.
 4. Place a shortcode block on a post and set its size, the plugin supports
 "light", "medium", and "heavy", which respectively create an HTML table
 with 500, 1000, and 10,000 rows. The shortcode should look like this:
 [table_perf_test size="heavy"].
 5. Go to the page on the frontend and view the page generation time in
 Query Monitor after hitting refresh.

 Repeat step 5 for each environment and compare the results.
