drush xmlsitemap:regenerate does not work with Config ReadOnly active

Problem/Motivation

I would like to regenerate the sitemap.xml on a website which has Config ReadOnly enabled.
This is currently not possible because I get the following error:

-> % drush xmlsitemap:regenerate
>  [notice] https://mysite.local/sitemap.xml?page=1 wurde mit 535 Links erzeugt.
> 
> In ConfigReadonlyStorage.php line 142:
>                                                              
>   Your site configuration active store is currently locked.  
>                                                              
> 

In ProcessBase.php line 155:
                    
  Output is empty.  
                    

This also seems to be a problem when the regeneration process is being triggered via Drupal Cron because I get the following error in the watchdog

Drupal\config_readonly\Exception\ConfigReadonlyStorageException: Your site configuration active store is currently locked. in Drupal\config_readonly\Config\ConfigReadonlyStorage->checkLock() (line 142 of /home/purecnbk/dev/docroot/modules/contrib/config_readonly/src/Config/ConfigReadonlyStorage.php).
