Update: Increase footnotes meta priority and separate footnotes meta registration.

[jorgefilipecosta]

This PR does two actions:

• Separates the footnotes meta registration from the block registration.
• Increases the priority of the registration to 20.

Most post types are registered on init with a priority of 10 having a priority of 20 makes sure the footnotes meta is registered for all of the post types with a priority of 20. While also allowing plugins to change the footnotes meta if they have an advanced need ( as long as they use a priority higher than 20).

Testing Instructions

• In the core install you are using to test Gutenberg comment the line add_action( 'init', 'register_block_core_footnotes' ); in src/wp-includes/blocks/footnotes.php (otherwise, the meta is registered there anyway).
• Verify it is still possible to add footnotes to a post.

Maybe??

Suggested change

	function wp_register_footnotes_post_meta() {
	function register_block_core_footnotes_post_meta() {

I'm unclear why the post types are limited to public. If someone has a private post type using the block editor, they probably want access to footnotes.

That said, if there are reasons then post types can be public but not actually public. You'll need to change the code below to:

	$post_types = get_post_types( array( 'show_in_rest' => true ) );
	$post_types = array_filter( $post_types, 'is_post_type_viewable' ) );

Outside the diff sorry so can't do an inline suggestion

Hi @peterwilsoncc, your points are well taken! Footnotes work even on non-public post types, so I removed the public filter. I also updated the function name. Thank you for the suggestions 👍

@jorgefilipecosta Sorry, I missed this at the time -- comments should start with /* (a single asterisk) rather than a double asterisk). The latter is used for docblocks only to allow them to be picked up by parser for developer.wordpress.org

Are you able to do a follow up commit.

[jorgefilipecosta]

Sure doing a follow up fix, thank you for catching this 👍

Note that as part of curating the Gutenberg 17.8 changelog, I added the labels [Type] Enhancement and [Block] Footnotes to this PR to better categorize it.

Please let me know if there is a different label that would be a better fit.
