Same provider address on multiple address provider

[antiseptikk]

Hi,

I found a problem in the display of addresses from the MetadataType form.
The data displayed in all blocks corresponds to the data of the last provider displayed.

I solved the problem very quickly by adding a clone on the provider :

private function addShippingAddressProviderFormViewVars(FormView $view, ShippingMethodInterface $method): void
    {
        if ($method instanceof AddressProviderAwareInterface && null !== $method->getShippingAddressProviderConfiguration()) {
            $provider = clone $this->addressProviderFactory->createFromConfiguration($method->getShippingAddressProviderConfiguration());
            $view->vars['address_provider_template'] = $provider->getShipmentMetadataTemplate();
            $view->vars['address_provider'] = $provider;
        }
    }

Here are a few screens.
