angular - 无法分配给对象的只读属性 'stopImmediatePropagation'

Question

将@angular/platform-b​​rowser(和其他@angular/xxx)升级到版本 6.0.4 后，我在应用程序的第一次加载和每次第一页重新加载后出现此错误(第一个 F5:错误，第二个 F5 : 工作):

NodeInvocationException: Cannot assign to read only property 'stopImmediatePropagation' of object '[object Object]' TypeError: Cannot assign to read only property 'stopImmediatePropagation' of object '[object Object]' at DomEventsPlugin.module.exports../node_modules/@angular/platform-browser/bundles/platform-browser.umd.js.DomEventsPlugin.patchEvent (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:60044:50) at new DomEventsPlugin (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:60031:15) at eval (ng:///AppModule/module.ngfactory.js:51:25) at _callFactory (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40373:28) at _createProviderInstance$1 (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40319:26) at resolveNgModuleDep (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40282:21) at _createClass (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40346:29) at _createProviderInstance$1 (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40316:26) at resolveNgModuleDep (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40282:21) at _createClass (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40352:32)

这是我的 vendor.js 中产生错误的代码:

DomEventsPlugin.prototype.patchEvent = function () {
    if (!Event || !Event.prototype) {
        return;
    }
    if (Event.prototype[stopMethodSymbol]) {
        // already patched by zone.js
        return;
    }
    var delegate = Event.prototype[stopMethodSymbol] =
        Event.prototype.stopImmediatePropagation;
    Event.prototype.stopImmediatePropagation = function () { <-- ERROR
        if (this) {
            this[stopSymbol] = true;
        }
        // should call native delegate in case
        // in some environment part of the application
        // will not use the patched Event
        delegate && delegate.apply(this, arguments);
    };
};

这是我的环境

• .NET 核心 2.1
• Angular 6.0.4
• Angular/Cli 6.0.8
• 网络包 4.12.0
• aspnet-prerendering 3.0.1
• aspnet-webpack 3.0.0

在开发模式下，我激活了 webpack 开发中间件，错误是否与 vendor 的创建时间有关？应用程序第一次加载时创建 vendor ，第二次从缓存中取出 vendor :
