Content Slider styles not loading when using Load CSS on demand

The Content Slider styles doesn’t load when this option is activated:
[x] Load CSS and JS of blocks on demand

I have noticed it is the only block that doesn’t have assets/blocks/content-slider/style.css, so I added an empty style.css and enqueued and that fixed the issue.

wp_enqueue_style(
	self::$blockName,
	getwid_get_plugin_url( 'assets/blocks/content-slider/style.css' ),
	['slick', 'slick-theme'],
	getwid()->settings()->getVersion()
);
