StablePosition was in some cases recording a wrong position, as it was
taking the framePosition and considering it to be the widget's
position. That erroneous position was then used to place the window,
resulting in a correct position but a wrong framePosition.
Wait and check for the window.geometry() and the
window.frameGeometry() to be different. If not the frame
has not been updated, or there is no frame when there
should be one. The test will most likely fail because
of this.
