Let's say we register the ux_live_component routes as following:

live_component:
    resource: '@LiveComponentBundle/config/routes.php'
    prefix: '/_components'
    defaults:
       _routeScope: ['storefront']
       _loginRequired: true 

When the \Symfony\UX\LiveComponent\Controller\BatchActionController::__invoke is invoking sub requests, it sets the only certain attributes. So that for example the _loginRequired and _routeScope defaults are skipped. I want to create a PR to address this issue but not sure where to look. As the defaults are added to the routes at compile time and the batchAction is invoking the requests directly so that the route matching (and default attributes logic) is skipped.
