Native export doesn't include Walls.Back.Brush.Gradient.Visible.

Ie, with two charts and a button on a form and this code, the default gradient is lost and the back looks different:

Private Sub Form_Load()  
  TChart1.Aspect.View3D = False
  TChart1.Legend.Visible = False
  TChart1.AddSeries scLine
  TChart1.Series(0).FillSampleValues
End Sub

Private Sub Command1_Click()
  TChart2.Import.LoadFromStream TChart1.Export.asNative.SaveToStream(True)
End Sub

A workaround is to manually copy the property, ie:

TChart2.Walls.Back.Brush.Gradient.Visible = TChart1.Walls.Back.Brush.Gradient.Visible

But this workaround has only sense when you still have access to the original chart, what can be impossible specially when you are working with .tee files.

Note this problem is probably related to #1015 as it worked fine until v2016.0.0.0:

Also note this is correctly exported in VCL. You can compare VCL and ActiveX outputs easily using the "View" button at the "Export\Native" tab in the respective editors at runtime.
