As it already was not possible to pass the required parameters without also passing the optional one anyway, removing the default value for the (not so) optional parameters should not affect backward compatibility. This change affects three functions in core: * `get_comment_delimited_block_content()` * `do_enclose()` * `_wp_delete_tax_menu_item()` Props jrf, ayeshrajans, desrosj. Fixes #50343. Built from https://develop.svn.wordpress.org/trunk@48794 git-svn-id: http://core.svn.wordpress.org/trunk@48556 1a063a9b-81f0-0310-95a4-ce76da25c4cd
