Scrollbar still crashable if one tries very hard. :-,(  Was tempted to open a
new MINOR bug, but maybe its easily fixable...

1. With LargeChange=0, drag the tab to the very end of the scrollbar.
2. Now Value==(Maximum+1), which it shouldn't be.  MSFT has Value==Maximum in
this case.
3. Secondly, now clicking either scrollbar-arrow or clicking in the scrollbar
causes a crash:
[[
Unhandled Exception: System.ArgumentOutOfRangeException: '101' is not a valid
value for 'Value'. 'Value' should be between 'Minimum' and 'Maximum' [@101->101
