Investigate issues with element type resolution

[ufukty]

The issue below contain an example JSON doc which contains an array of time series data. Seems like Gonfique Playground produces any as element type for it. The issue probably on the JSON doc, containing conflicting type of example values for the same target type. Although the doc is too big to manually review.

Those are the all element types Gonfique produces for the array:

There doesn't seem any collection item type that contradicts with its parent's sibling's corresponding item types.

Thus, the issue might be with nesting.
