Buttons, comboboxes and other charts disappearing when clipping at OnBeforeDrawSeries.

This affects the THighLowSeries, which internally uses OnBeforeDrawSeries to draw High and Low Brushes.

It can also be reproduced with a TLineSeries as in the attached example.

However, the clipping works fine using the LineSeries and doing the clipping calling SaveState, IntersectClipRect and RestoreState directly, which seems to be exactly what TeeChart's ClipRectangle and UnClipRectangle are doing. But only TeeChart's functions are giving problems here.
