Treema can't update parent containers when setting null values by changing schema selection

[nwinter]

There's no way to get the parent to update after I change worldEndsAfter from type: float to type: null.

I often used to have the same problem trying to save containers where I have changed a boolean, but at least then certain keyboard interactions to change the value will update the parent, so I could work around it. For null, there's no way to toggle a value change, so I can't save it.
