 When `WP_PLUGIN_DIR` has slightly different casing to the actual path,
 `plugin_basename()` returns the full path to the plugin file.

 For example:

 If `WP_PLUGIN_DIR` is set to `C:/Website/wp-content/plugins`, but the
 actual file-system path is `C:/Website/wp-content/Plugins`,
 `plugin_basename()` will return the full path to the plugin file.

 The `plugin_basename()` function uses a `preg_replace` statement to find
 path to the plugin relative from `WP_PLUGIN_DIR`. If the actual path to
 the plugin directory does not match case to `WP_PLUGIN_DIR`, the
 preg_replace will fail. This is because preg_replace is not case
 sensitive.
