when I open the Panel again.(open-close-open)
The contents on the panel all disappeared.(It will show when I double-click the panel area)
Please see the screen shot below.
This can be reproduced on real device(iOS7), test app.
But on browsers works well.

2.But,then I close the panel and open it again, all the contents on panel gone.
