"Styles Dropdown" entries get stripped by "Limit allowed HTML tags and correct faulty HTML"-Filter

Problem/Motivation

When working with the latest 8-rc3 predefined element styles, those custom css classes get removed if the filter for "Limit allowed HTML tags and correct faulty HTML" is activated. Thus, the rendered body text has no classes in the frontend and the styles dropdown in the ckeditor gets deactivated in the backend.

Workaround

Explicitly allow the "class" attribute to the elements you are styling. e.g. <a href hreflang class> <p class>

Remaining tasks

Revert former behavior: allowing classes defined by the styles modules.
