L10n problem

Hello, friends!
I am WP-programmer from Russia.
Seems what after recetly innovations in WordPress core, we have some problem with localization. I mean a new feature define language for user. After this, Woocommerce sometime use user-locale instead global-locale. For example, it affect to emails for WC-customer when order status changes – emails use user language instead site language.
Some problem with a lot of woocommerce descriptions.

As a temporaty solution for emails, I use this code

	add_action( 'wp_ajax_woocommerce_mark_order_status', 'repair__woocommerce_mark_order_status', 1 );
	function repair__woocommerce_mark_order_status(){
		$GLOBALS['wp_locale_switcher']->switch_to_locale( get_locale() );
	}
