### Current Behavior

I have found multiple bugs but I think they can be caused by the same issue: Layouts ignore set constraints when used inside of state container as a state.

| Layout | Layout not inside of state container (working) | Layout inside of the container (not working) |
| -- | -- | -- |
| Grid + Label |  |  |
| ScrollView |  | 
| ItemView |  |  |

But if set a specific height to that layout it shows up as:

These all seem like they originate from how the bounds of the sub-layouts are calculated if they are calculated at all.

### Expected Behavior

Images with expected behavior are in the previous paragraph.

### Steps To Reproduce

I included an application repository where you can try working and not working layouts.

1. We can just run without doing any edits why launches the app which is using a state container.
2. If we want to see working constraints we can uncomment the Working Constraints region.
3. If we want to see a working Scroll View we can uncomment the Working Scroll View region.
4. If we want to see a working refresh view we can uncomment the Working Refresh View region.
