Quickcontrols 2 StackView push without properties

[Rukshan Perera]

I want to use the API "Item pushItem(item, properties, operation)" without properties.
I tried different approaches. But nothing works. How to send an empty property or avoid sending property for the API, but the operation.

stackView.pushItem(item, {}, StackView.Immediate);
stackView.pushItem(item, undefined, StackView.Immediate);

I can do below with push for now and seems to be working, but I would like to have strong type checking nature of pushItem.

stackView.push(item, undefined, StackView.Immediate);
