Using register_block_type_from_metadata requires extra filter

[coderaaron]

Thank you so much for this! I've been trying to build something similar on my own but not having much success.

If you use register_block_type_from_metadata to register a block it does property mappings and will discard any value passed in for ssr (see line 230 in wp-includes/blocks.php).

To get around this I added this filter.

add_filter(
	'block_type_metadata_settings',
	function( $settings, $metadata ) {
		if ( isset( $metadata['ssr'] ) && $metadata['ssr'] == true ) {
			$settings['ssr'] = true;
		}
		return $settings;
	},
	10,
	2
);
