I've followed this guide to setup settings.local.php: https://www.drupal.org/node/2598914
And in my custom subtheme I have a stylesheet style.css which is working correctly. However when I look in the network tab in Chromium I see that the file is being renamed and loaded as the following instead of style.css
Is there a way to stop this renaming using settings.local.php during development? I've tried turning off css aggregation through the GUI but I believe the changes in settings.local.php override this anyway?
