MiniCart Widget – Modal Popup not displaying

Recalling the Issue #53, on desktop when clicking the button on the mini-cart widget, the Paypal In-Context Checkout modal window doesn’t pop up, instead the checkout continues in the same browser window. Instead the modal iFrame should open and a black layer should overlay the website on background, exactly like if the button is pressed on the cart page.

Tested with StoreFront, other themes, WooCommerce 3.2.x and the Official plugin WooCommerce PayPal Express Checkout Gateway 1.4.4.

I don't know, I suppose there is some condition not passed correctly when calling https://www.paypalobjects.com/api/checkout.js.
May it be that in 'class-wc-gateway-ppec-cart-handler.php', the priority must be higher? add_action( 'woocommerce_widget_shopping_cart_buttons', array( $this, 'display_mini_paypal_button' ), 20 );

Or that something can be corrected here:

/* Display paypal button on the cart widget*/
public function display_mini_paypal_button() {

    $gateways = WC()->payment_gateways->get_available_payment_gateways();
    $settings = wc_gateway_ppec()->settings;

    // billing details on checkout page to calculate shipping costs
    if ( ! isset( $gateways['ppec_paypal'] ) || 'no' === $settings->cart_checkout_enabled ) {
        return;
    }
    ?>
    <a href="<?php echo esc_url( add_query_arg( array( 'startcheckout' => 'true' ), wc_get_page_permalink( 'cart' ) ) ); ?>" id="woo_pp_ec_button" class="wcppec-cart-widget-button">
        <img src="<?php echo esc_url( 'https://www.paypalobjects.com/webstatic/en_US/i/btn/png/gold-rect-paypalcheckout-26px.png' ); ?>" alt="<?php _e( 'Check out with PayPal', 'woocommerce-gateway-paypal-express-checkout' ); ?>" style="width: auto; height: auto;">
    </a>
    <?php}

Or in wc-gateway-ppec-frontend-in-context-checkout.js

if ( wc_ppec_context.show_modal ) {
    $wc_ppec.init();
}
