hasNativeControl is kind of confusing, since above there's a setNativeControlAttr, which implies there's always a native control. I think this field needs more documentation to explain what information it is conveying, and how that interacts with other things.

Similarly, setNativeControlDisabled probably has implications for the behavior of setNativeControlAttr, please document.

Or maybe it's setting the disabled state of the native control? In which case it definitely needs documentation due to the ambiguity. And then documentation of how this is different from setNattiveControlAttr('disabled')
