### Steps to reproduce

_Please write down the steps to reproduce. Try to write down all necessary preconditions (what permissions do you have, are other users involved?). Example:_

1. Login as an admin user

2. Navigate to the work package - types - select a random type (e.g. _task_) and change the default description as following

1. switch to Markdown mode

2. add this template


```text
# Aufgabenbeschreibung

<Grobe Beschreibung>

# Warum ist das wichtig?

<Kurze Begründung für das "Warum".>

# Bearbeitungsstand & Ergebnisse

<Wann ist die Aufgabe "fertig"?>

* [ ] TODO 1
* [ ] Teil-TODO 1
* [ ] Teil-TODO 2
* [ ] Hier sollte ein Beispiel erstellt werden, wie eine erledigte Aufgabe aussehen kann.
**Ergebnis:** So könnte es aussehen.
* [ ] TODO 2
* [ ] ...

3\. save this new default work package description

4\. Create a new work package from the type you just altered. Give it a subject and save it.
5\. Open the work package description and select one of the ul list items (TODO 1).
6\. Make a checkbox out of this list item.
7\. Save

### What is the buggy behavior?

_Please describe the bug in as much detail as possible. Example:_

* The list reverts back to the default template type.

* This seems to happen with other transitions as well (see gif). It seems like list types lose made changes after they have been edited saved and then reverted back to edit mode.


### What is the expected behavior?

_Describe how the application should behave like. Example:_

1. The chosen list type is displayed in edit and viewer mode of a work package description.
