Configure Ember CLI Mirage to support liverload for mirage configuration with Embroider

I have an Ember.js application, which uses Embroider and Ember CLI Mirage. Sadly live-reload is not working for Mirage configuration changes. A change to Mirage configuration does not trigger a rebuild. It seems as if mirage/ folder is not watched.

I reproduced this issue in a newly created Ember application using Ember CLI v4.1 with the --embroider flag. So it is not related to any special configuration of my application.

Do I need to configure Embroider somehow to watch mirage/ folder?
