Button MouseEvent PointEvent AbsolutePosition return {0 0}

[Claudio08]

Describe the bug:

Is right that "MouseEvent PointEvent AbsolutePosition return always {0 0}"?

I trap the mouse position on a button widget to retrive the absolute Position of the myButton
using the following function:

Example code:

func (b *myButton) MouseIn(em *desktop.MouseEvent) {
    fmt.Println("MouseEventAbsolutePosition ", em.AbsolutePosition)
    fmt.Println("MouseEventPosition ", em.Position)
    fmt.Println("Button Position() ", b.Position())
    fmt.Println("AbsolutePositionForObject ", fyne.CurrentApp().Driver().AbsolutePositionForObject(b))
}

the result is:
MouseEvent PointEvent AbsolutePosition: return always {0 0}
MouseEvent PointEvent Position: return variable position mouse value example {6 28}
Button Position: return always {0 33}
AbsolutePositionForObject: return the exact position in the window of myButton {4 132}
