[Bug]: Dragging a List Widget Inside Another List Widget Crashes the App

Is there an existing issue for this?

Description

Although currently, nested lists are not supported, if the user resizes a list, they can make it fit inside another list, which makes the app crash. Users should not be allowed to add a list widget inside another list widget unless nested lists will be supported.

Steps To Reproduce

1. Add a List widget to the canvas.
2. Add a second List widget to the canvas.
3. Resize one of the List widgets, decreasing its size until it fits inside the item of the other List widget.
4. Drag it inside the "parent" List widget and drop it once it's not highlighted with red anymore.
5. Note that the app crashes and console errors get displayed.

Thanks for adding! :)

FYI: In this same manner, it is possible to nest a Table Widget inside a List widget. The app does not crash in this case, but this operation should probably not be allowed.

@Tooluloope is it possible to fix this independently without solving it in list widget epic?

Note: Fixed in List v2 POC.
