Hello @Torben Hansen, your update worked fine in TYPO3 versions 12.4.7 and 12.4.8. With the release of 12.4.9, custom HTML gets lost again (tested in 2 installations).
I use the "allow all" configuration:
https://ckeditor.com/docs/ckeditor5/latest/features/html/general-html-support.html#enabling-all-html-features

Could you take a look into this? I guess it could be very suprising to lose custom HTML or classes on saving an element. Should I open a separate ticket for this?

@Andreas Krämer Please create a new ticket for the problem, since this issue is closed already
