QAbstractScrollArea: When calling mapToGlobal() on the viewport after setGeometry() is called on the scrollarea can return incorrect values

QAbstractScrollArea: When calling mapToGlobal() on the viewport after setGeometry() is called on the scrollarea can return incorrect values. Calling geometry() and frameGeometry() shows that the window has indeed moved, but calling mapToGlobal() on the viewport can give values that refer to the old location.

In the example, to reproduce it just click on the window when it is visible and see the output.
