Symfony version(s) affected

7.3.0

Description

I'm trying to use the new alias introduced on the #[Route] attribute in 7.3, but getting unexpected results.

How to reproduce

with configuration

# config/routing.yaml
general:
  resource: '../src/Controller/'
  type: attribute
  prefix:
    nl_NL: /
    nl_BE: /
    fr_FR: /
    fr_BE: /fr
    en_US: /
  host:
    nl_NL: '%nl_host%'
    nl_BE: '%be_host%'
    fr_FR: '%fr_host%'
    fr_BE: '%be_host%'
    en_US: '%en_host%'

using

#[Route(path: [
    'nl_NL' => '/',
    'nl_BE' => '/',
    'fr_FR' => '/',
    'fr_BE' => '/',
    'en_US' => '/',
], name: 'default', methods: ['GET'], alias: ['my-alias'])]

yields Target route "default" for alias "my-alias" does not exist. from the template where i try to generate url(app.current_route)

but using

#[Route(path: '/', name: 'default', methods: ['GET'], alias: ['my-alias'])] 

yields Unable to generate a URL for the named route "my-alias" as such route does not exist. later on in the same template when trying to generate url('my-alias')
