As a user I want cloned details if I edit details from previous minutes in the current minutes because I do not want to lose information in the "topic all time history".

If details (with an older time stamp) are available in the current minute and user triggers "edit details":
1.) Make a clone of the details
2.) Give the clone a fresh time stamp
3.) Open markdown editor on the clone

• It is not possible to change details of older minutes
• If the details have been added in the current minute (either by clone or by "Add details") they can be edited without cloning
• Old or new/cloned details can be deleted
