Problem description
When using records which contain a leading number in the record slug, url routing for detail/show action leads to the following error:

#1298012500 TYPO3\CMS\Extbase\Mvc\Controller\Exception\RequiredArgumentMissingException
Required argument "job" is not set for VendorName\PluginName\Controller\JobController->show.
in /path-to-site/typo3/sysext/extbase/Classes/Mvc/Controller/AbstractController.php line 414

An example of a url which causes the error:

https://some-domain.com/jobs/detail/30-lorem-ipsum-job-slug/

Route config looks like this:

routeEnhancers:
  Job:
    type: Extbase
    namespace: tx_xyjobs_pi1
    routes:
      -
        routePath: '/{jobtitle}'
        _controller: 'Job::show'
        _arguments:
          jobtitle: job
      -
        routePath: '/job-page/{page}'
        _controller: 'Job::list'
        _arguments:
          page: '@widget_0/currentPage'
    defaultController: 'Job::list'
    defaults:
      page: '1'
    aspects:
      page:
        type: StaticRangeMapper
        start: '1'
        end: '1000'
      jobtitle:
        type: PersistedAliasMapper
        tableName: tx_xyjobs_domain_model_job
        routeFieldName: slug

This issue also occurs in the News extension.

I may be missing something, but surely this is not the desired behaviour?
