innerBlocks widget areas do not get saved

Hi,
works great but can’t use it in columns block or any nested block.

I updated classes/widget-area.php to search the blocks recursively:

	/**
	 * Save newly added widgets in options on post save.
	 *
	 * @param int    $post_id post id.
	 * @param object $post
	 * @param string $update
	 */
	public function update_widgets_log( $post_id, $post, $update ) {
		// Check if user has permissions to save data.
		if ( ! current_user_can( 'edit_post', $post_id ) ) {
			return;
		}

		// Check if not an autosave.
		if ( wp_is_post_autosave( $post_id ) ) {
			return;
		}

		// Check if not a revision.
		if ( wp_is_post_revision( $post_id ) ) {
			return;
		}

		$saved_widgets = get_option( self::$option_name, [] );

		$blocks = parse_blocks( $post->post_content );

		if ( isset( $saved_widgets[ $post_id ] ) ) {
			unset( $saved_widgets[ $post_id ] );
		}

		$saved_widgets = self::find_saved_widgets_recursive( $saved_widgets, $post_id, $blocks );

		update_option( self::$option_name, $saved_widgets, true );

	}

	/**
	 * Walk the post content blocks recursively and find widget area blocks.
	 *
	 * @param array	$saved_widgets
	 * @param int	$post_id		post id.
	 * @param array	$blocks
	 * @return array	$saved_widgets
	 */
	protected static function find_saved_widgets_recursive( &$saved_widgets, $post_id, $blocks ) {

		if ( ! empty( $blocks ) ) {
			foreach ( $blocks as $block ) {
				if ( isset( $block['blockName'] ) && self::$block_name === $block['blockName'] ) {
					if ( '' !== trim( $block['attrs']['widget_area_title'] ) ) {
						$saved_widgets[ $post_id ][] = $block['attrs']['widget_area_title'];
					}
				} elseif ( isset( $block['innerBlocks'] ) && ! empty( $block['innerBlocks'] ) ) {
					self::find_saved_widgets_recursive( $saved_widgets, $post_id, $block['innerBlocks'] );
				}
			}
		}

		return $saved_widgets;
	}

This solves the issue.
Can’t find the git repository to fork it.

Thanks
