TYPO3 Core

I am not sure weather this is a bug or lack of documentation. I tried to configure the ckeditor to allow any classes for all tags by first trying to allow everything with the following yaml configuration:

editor:
  config:
    htmlSupport:
      allow:
        - { name: "/.*/", attributes: true, classes: true, styles: true }

As well different syntax has been tried but it didn't work.
