${PostType}EditorBlock Interfaces are being registered and implemented with different names

[jasonbahl]

Note:

I had the following post type:

add_action( 'init', function() {
	register_post_type( 'event', array(
	'labels' => array(
		'name' => 'Events',
		'singular_name' => 'Event',
		'menu_name' => 'Events',
		'all_items' => 'All Events',
		'edit_item' => 'Edit Event',
		'view_item' => 'View Event',
		'view_items' => 'View Events',
		'add_new_item' => 'Add New Event',
		'new_item' => 'New Event',
		'parent_item_colon' => 'Parent Event:',
		'search_items' => 'Search Events',
		'not_found' => 'No events found',
		'not_found_in_trash' => 'No events found in Trash',
		'archives' => 'Event Archives',
		'attributes' => 'Event Attributes',
		'insert_into_item' => 'Insert into event',
		'uploaded_to_this_item' => 'Uploaded to this event',
		'filter_items_list' => 'Filter events list',
		'filter_by_date' => 'Filter events by date',
		'items_list_navigation' => 'Events list navigation',
		'items_list' => 'Events list',
		'item_published' => 'Event published.',
		'item_published_privately' => 'Event published privately.',
		'item_reverted_to_draft' => 'Event reverted to draft.',
		'item_scheduled' => 'Event scheduled.',
		'item_updated' => 'Event updated.',
		'item_link' => 'Event Link',
		'item_link_description' => 'A link to a event.',
	),
	'public' => true,
	'show_in_rest' => true,
	'supports' => array(
		0 => 'title',
		1 => 'editor',
		2 => 'thumbnail',
	),
	'delete_with_user' => false,
	'show_in_graphql' => true,
	'graphql_single_name' => 'testEvent',
	'graphql_plural_name' => 'testEvents',
) );
} );

And this lead to the following GraphQL Types being registered:

• TestEvent
• EventEditorBlock

Then the TestEvent.editorBlocks field attempted to return a list_of TestEventEditorBlock but since that type doesn't exist, we would see the graphql debug error (and maybe more errors depending on the query we tried to execute).
