<p>When you run <code>drush site:export</code>, you will get something like <code>//front</code> as the <code>system.site:page.front</code> config value.</p>
<p>This is because <code>\Drupal\drupal_cms_helper\GenericConfigurationListener</code> prepends an extra slash. I think this might have been necessary at some point, but it's interfering when the alias manager returns an alias.</p>
