RX.UserInterface.measureLayoutRelativeToAncestor differs in measuring scroll for platforms

[ghost]

Method RX.UserInterface.measureLayoutRelativeToAncestor gives different results for Electron and Web than for UWP, Android and iOS when measuring two elements where one is in a scrollable container (RX.ScrollView).

• For Electron & Web returns true distance on screen (scroll is accounted for).
• For UWP, Android and iOS returns distance "in DOM" meaning for same two elements A&B the same result is returned every time regardless of the actual scroll position of the RX.ScrollView.

  <RX.View id="A">
  <RX.ScrollView>
      ... lot of elements ...
      <Component id="B" />
      ... more elements ...
  </RX.ScrollView>
  RX.View>

  In comparison to that - method RX.UserInterface.measureLayoutRelativeToWindow gives always true distance on screen for all platforms.

I have a similar case, where RX.UserInterface.measureLayoutRelativeToWindow also do not provide correct information on mobile:

console.log('Will measure scrollview', scrollView)

RX.UserInterface.measureLayoutRelativeToWindow(scrollView).done((layoutinfo:RX.Types.LayoutInfo) => {
    console.log('Did measure scrollview', layoutinfo)
})

In web (Electron) this works out completly correct. On mobile all values received from the LayoutInfo are 0.

Looking forward to see a solution on this. :-)
