ryelle 5d983ec85b Help/About: Run image comparison script after all assets have loaded. 
If the callback is called before the images are loaded, the comparison doesn't work. `wp.domReady` uses `DOMContentLoaded`, which does not guarantee that the images are loaded. This switches to use the `load` event, which waits for all resources to load.

Peter Wilson 0b9c7b7cdf Site Health: Update loopback test to `POST` to wp-cron. 
Replace loopback health check URL with a `POST` request to `wp-cron.php` in the WordPress install directory. This more closely represents how WordPress uses loopback requests.

A `POST` request is used to cause `wp-cron.php` to exit prior to running any cron jobs. This allows the test to indicate success quicker and accounts for sites that set the `DISABLE_WP_CRON` constant to avoid running cron jobs on loopback requests.

Sergey Biryukov dbaee6b550 Filesystem API: Make sure to only call `fread()` on non-empty files in the PclZip library. 
This avoids a fatal error on PHP 8 caused by passing a zero value to `fread()` as the `$length` argument, which must be greater than zero.

When working on changes to @wordpress/create-block tool (https://github.com/WordPress/gutenberg/pull/28883) to use register_block_type_from_metadata with block.json file in the templates for scaffolded blocks I run into this issue where apiVersion wasn't exposed from the server.

Sergey Biryukov ea2ff553e9 Site Health: Clarify the recommendation in file uploads test when `post_max_size` is defined as `0`. 
This adds a more descriptive text in scenarios where `post_max_size` and `upload_max_filesize` differ, and `post_max_size` is set to a value of `0`.

In some scenarios, PHP may read `0` as a literal zero size, and not as unlimited, which it also means in other scenarios.

See https://www.php.net/manual/en/ini.core.php#ini.post-max-size for details, as PHP 5.3.4 introduced this behavior for literal zero interpretation when the content type of a request is `application/x-www-form-urlencoded` or is not registered with PHP.
