LinearGradientBrush has an issue when it runs on WebBrowser. But in the simulator works correctly. Simulator works equals to my WPF application.
<LinearGradientBrush StartPoint="0,0" EndPoint="1,0">
<GradientStop Color="#FF99CCFF" Offset="0" />
<GradientStop Color="#FF000000" Offset="1" />

On the Simulator: OnTheSimulator.png
Note: On the WebBrowser seems inverted.
Can you reproduce this issue ? Is it possible fix it to next release 2.0 088 ? I have many fill's and background's with gradient (Linear and Radial) and that is important to me.
