ckeditor extension: Custom inline elements are not upcasted correctly in tables (tableCell) and with autoparagraph: false in $root

[mhsdesign]

Ckeditor extension point:

Custom inline elements are not upcasted correctly in tables (tableCell) and with autoparagraph: false in $root

See ckeditor/ckeditor5#6698 (comment) for more detail.

This bug is fixed via ckeditor/ckeditor5#7753 in Ckeditor 22 but we still use 16

There is a workaround described here: ckeditor/ckeditor5#6698 (comment)

The question is if we should add this fix/workaround into our codebase? (This would be a better option that multiple people defining this themselves -> which is unlikely but still ...)
