FMX project with a series and ScrollPager tool

Having a Firemonkey project with a TScrollPagerTool, doesn't let the chart resize when the form is resized and the chart is aligned to alClient. Attached a simple example project reproducing this.

Maybe this is related to .NET issue 72:

No, this doesn't work here. Actually, ScrollPager tool resizes correctly in a VCL project but doesn't in a Firemonkey project.

I get the same problem in VCL and FireMonkey with latest sources. 
When chart is resized, layout is not reconstructed.

There is a workaround but it'd be better if the tool can do it internally automatically, remembering the "old" chart size and resizing if different.

procedure TForm1.Chart1Resize(Sender: TObject);
begin
  ChartTool1.SetUpScrollPager;
end;

Fixed. When the chart is resized (or maximized), the scrollpager tool will re-layout.

Still pending to find a good way to improve the alignment of both axes (the main chart and the scrollpager subchart).  Right now the margins are hardcoded (ie:  25 pixels horizontal, etc), so when for example an axis labels font size is bigger than the other, the alignment is not perfect.
