error occured while close webview window

[ericjing83]

Dear sir,

I have tested gowebview on my win10 laptop. And, the golang program is able to open a new window for a predefined website.
But, the problem is that, when I close the webview main window, an error occurs:
[0119/193101.014:ERROR:window_impl.cc(119)] Failed to unregister class Chrome_WidgetWin_0. Error = 0
