为什么将 FEATURE_BROWSER_EMULATION 设置为 IE10 或 IE11 时，Visual Studio 中的 Web 浏览器控件会出现故障？

const int POLL_DELAY = 250;
WebBrowser _webBrowser;

// set WebBrowser features, more info: http://stackoverflow.com/a/18333982/1768303
static void SetWebBrowserFeatures()
{
    // don't change the registry if running in-proc inside Visual Studio
    if (LicenseManager.UsageMode != LicenseUsageMode.Runtime)
        return;

    var appName = System.IO.Path.GetFileName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);

    var featureControlRegKey = @"HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\";

    Registry.SetValue(featureControlRegKey + "FEATURE_BROWSER_EMULATION",
        appName, GetBrowserEmulationMode(), RegistryValueKind.DWord);

    // enable the features which are "On" for the full Internet Explorer browser

    Registry.SetValue(featureControlRegKey + "FEATURE_ENABLE_CLIPCHILDREN_OPTIMIZATION",
        appName, 1, RegistryValueKind.DWord);

    Registry.SetValue(featureControlRegKey + "FEATURE_AJAX_CONNECTIONEVENTS",
        appName, 1, RegistryValueKind.DWord);

    Registry.SetValue(featureControlRegKey + "FEATURE_GPU_RENDERING",
        appName, 1, RegistryValueKind.DWord);

    Registry.SetValue(featureControlRegKey + "FEATURE_WEBOC_DOCUMENT_ZOOM",
        appName, 1, RegistryValueKind.DWord);

    // Disable FEATURE_NINPUT_LEGACY_MODE
    Registry.SetValue(featureControlRegKey + "FEATURE_NINPUT_LEGACYMODE",
        appName, 0, RegistryValueKind.DWord);
}
