QtCharts/QXYSeries::colorBy method behave incorrectly after points are selected in QScatterSeries.

When a scatter series has some currently selected points (with series selection color set different from marker color) and colorBy method is called, scatter points appear as expected at first. But on trying to resize the chart window, selection color is no longer visible on the points as if they are not selected.
(However selection color remains intact if colorBy method was not called.)

Attached sample code to reproduce the above problem. Try resizing the window to see the bug.
