Subject: [PATCH 22/85] Migrate ckeditor5-coremedia-studio-integration-mock
 package to node test runner - IMPORTANT: The tests are not finishing right
 now. This might be due to open connections / subscriptions in serviceAgent /
 MockContentDIsplayService etc.

Subject: [PATCH 23/85] Migrate ckeditor5-font-mapper package to node test
 runner - IMPORTANT: The tests are not finishing right now. This might be due
 to open connections / subscriptions in serviceAgent /
 MockContentDIsplayService etc. - FAILING TEST: FontMapping test fails for
 most of the mapping table
