Show/hide section in theme customizer based on selection from another section

In this example, estore_is_cart should return true only if 'suspended' === $wp_customize->get_setting( 'twsa_show_schedule' )->value(). Or in other words:

$wp_customize->add_control( 'twsa_show_suspend', array(
    'description' => 'Reason for suspension',
    'section' => 'twsa_show',
    'type' => 'textarea',
    'active_callback' => function() use ( $wp_customize ) {
        return 'suspended' === $wp_customize->get_setting( 'twsa_show_schedule' )->value();
    },
));
