DMN Editor can not reopen List expression

[jomarko]

To reproduce the issue please follow the steps:

1. open new DMN model
2. add a decision node
3. define the decision node as List expression
4. close the DMN model
5. reopen the node
6. try to open the decision node that is internally defined as List expression

I confirm that this issue is also reproducible in the current main, but I was unable to reproduce if the list expression is not empty (if it have an inner expression inside of each row).
