Debugging 在Windows 10中使用UI自动化时内存泄漏

我在Windows 10计算机上遇到内存泄漏问题，在调查导致该问题的进程（WPF应用程序）中的一些转储后，我发现“MS.Internal.Automation.SynchronizedInputProviderWrapper”的许多实例，基本上，内存中保存但未收集垃圾的大多数对象都被该类型引用

我一直在使用dotMemory（实例的关键保留路径）、Visual Studio 2019（用于转储比较）和WinDbg进行进一步调查

根据这个答案：

他们的汇总解决了Win 8 RT&windows 2012服务器上的问题：

根据微软的说法：

当使用UI自动化框架的多个应用程序 在基于Windows 8的计算机上同时运行时，内存泄漏 发生，并且您的CPU使用率很高

我认为Windows 10上可能也存在同样的问题，但无法找到修复或汇总来修复此问题

更新：

我对SuperDump进行了另一次分析，发现了内存泄漏的可能原因，但我无法解释调用堆栈：
