C# 在TabControl中的选项卡之间切换后，浏览器将显示空白页

我正在32位WPF应用程序中使用CefSharp。我使用CefSharp作为文档查看器，它显示本地HTML和PDF文件。每个浏览器实例都嵌入到一个选项卡中（使用WPF TabControl）

在版本63.0.3中，一切正常。更新到73.1.130后，我遇到以下问题：打开一些选项卡并在它们之间切换后，浏览器在所有选项卡中显示一个空白页。

注意：在WPF中，从选项卡切换到选项卡会导致重新加载选项卡内的所有控件

我发现解决这个问题的唯一方法是再次降级到63.0.3

CefSharp在App.xaml.cs中初始化：

var cefSettings = new CefSettings()
{
  LogSeverity = LogSeverity.Verbose
};
var customScheme = new CefCustomScheme
{
  SchemeName = CustomProtocolSchemeHandlerFactory.SchemeName,
  SchemeHandlerFactory = new CustomProtocolSchemeHandlerFactory(),
  IsCSPBypassing = true
};
cefSettings.RegisterScheme(customScheme);
Cef.Initialize(cefSettings);

浏览器是这样嵌入的：

<wpf:ChromiumWebBrowser
    x:Name="WebBrowser" 
    HorizontalAlignment="Stretch" 
    Address="{Binding Address, Mode=TwoWay}"
    Title="{Binding Titel, Mode=OneWay}"
    AllowDrop="True"
    WebBrowser="{Binding WebBrowser, Mode=OneWayToSource}"/>

多亏了amaitland（见评论），这在版本73-中是一个问题。版本71没有此问题。

这是一个已知问题
