Describe the bug
When you copy a task list from the Details section from one card to another, the task list marks change into an unordered list.

To Reproduce
Steps to reproduce the behavior:

1. Go to a card with a task list in the Details section
2. Copy the task list
3. Paste the task list in another cards' Details section
4. The copied task list changes into an unordered list. information about tasks that are marked is lost.
5. To change into task list then you have to undo unordered list en activate task list. Still, information about tasks that were marked is lost.

Expected behavior
When you copy a task list in Details from one card to another, you expect that the task list including information about checkboxes stays in tact. We use this option a lot and previously used markdown editing which could be copied perfectly. For us this is a big problem.
