 The `$page` parameter of `Walker_PageDropdown->start_el()` is a `WP_Post`
 object. No modifications are performed in the function to the `$page`
 variable.

 When `$page` is passed to the `list_pages` filter at the end of the
 function, it is noted as an `object`. This could be more specific and
 indicate `$page` is a `WP_Post`.
