 == Test Report
 Patch tested: https://github.com/WordPress/wordpress-develop/pull/4742

 === Steps to Reproduce or Test
 1. Check out PR branch.
 2. Run `npm install && npm run build:dev`.
 3. In `wp-config.php`, set `SCRIPT_DEBUG` to `false`.
 4. Load the editor in a post or site editor.

 === Expected Results
 - ✅ The editor should load without error.

 === Environment
 - Hardware: MacBook Pro Apple M1 Pro
 - OS: macOS 13.4.1
 - Browser: Safari 16.5.1, Google Chrome 114.0.5735.133
 - Server: nginx/1.25.0
 - PHP: 7.4.33
 - WordPress: 6.3-alpha-56078-src

 === Actual Results
 - ✅ Editor loads without PHP errors.

 === Additional Information
 - The following JS warnings were logged in the console when `SCRIPT_DEBUG`
 is `false`:

  DevTools failed to load source map: Could not load content for http://wp-
 src.test/wp-admin/hooks.js.map: Unexpected token '<', "<!DOCTYPE "... is
 not valid JSON

  DevTools failed to load source map: Could not load content for http://wp-
 src.test/wp-includes/js/underscore-umd.js.map: Unexpected token '<',
 "<!DOCTYPE "... is not valid JSON

  was added to the iframe incorrectly. Please use block.json or
 enqueue_block_assets to add styles to the iframe.
  `<link rel="stylesheet" href="http://wp-src.test/wp-admin/load-

 - When `SCRIPT_DEBUG` is set to `true`, only the `underscore-umd.js.map`
 notice remains.
