Electron version: 1.2.0
Operating system: Windows 10 x64

When I invoke the webview executeJavaScript method under Electron 1.2.0 it appears as though my code is not executed. If I execute the method under Electron 1.1.3 everything is okay and my code gets executed.

atom/renderer/atom_renderer_client.cc
content::RenderFrame* render_frame,
    const std::string& mime_type,
    const GURL& original_url) {
  if (mime_type == content::kBrowserPluginMimeType) {
    return new GuestViewContainer(render_frame);
  } else {
    return nullptr;
  }
}
void AtomRendererClient::AddKeySystems(
    std::vector<media::KeySystemInfo>* key_systems) {
  AddChromeKeySystems(key_systems);
}
void AtomRendererClient::GetNavigationErrorStrings(
    content::RenderFrame* render_frame,
    const blink::WebURLRequest& failed_request,
    const blink::WebURLError& error,
    std::string* error_html,
    base::string16* error_description) {
  if (!error_description)
    return;
  *error_description = base::UTF8ToUTF16(net::ErrorToShortString(error.reason));
}
}
