Sortable field in text mode has stopped working

Hi Dōvy,

First of all thanks for releasing Redux Framework v4

However, I’m experiencing an issue with sortable field in text mode. Text box input changes are not saved inside the sortable field. Please check next short screencast https://take.ms/eN15I

I’m using default sortable field from the docs

// Header Social Links
Redux::setSection( $opt_name, array(
	'title'      => esc_html__( 'Social Links', 'redux-framework-demo' ),
	'subsection' => true,
	'id'         => 'subsection-header-social',
	'fields'     => array(
		array(
			'id'       => 'text-sortable',
			'type'     => 'sortable',
			'title'    => __('Sortable Text Option', 'redux-framework-demo'),
			'subtitle' => __('Define and reorder these however you want.', 'redux-framework-demo'),
			'desc'     => __('This is the description field, again good for additional info.', 'redux-framework-demo'),
			'mode'     => 'text',
			'options' => array(
					'1' => 'Item number one',
					'2' => 'Number two here',
					'3' => 'Three strikes, yer out!',
			),
		),
	)
) );

Hope you can help me to sort this out.

Best Regards!
