KB4338825-更新后，Word加载项将无法正常工作

Question

自KB4338825起，我们在Word OfficeJs-Addin中发现了一些错误。 安装更新后，我们可以在多台计算机上重现此问题。

我们的环境是：

- Windows 10 Enterprise x64 Version 1803 (Build 17134.165)
- Nodejs v8.9.4 LTS
- Office-JS v1.1.3-beta-next.4
- Angular CLI: 1.7.3
- Angular: 5.2.8
- @angular/cli: 1.7.3
- @angular-devkit/build-optimizer: 0.3.2
- @angular-devkit/core: 0.3.2
- @angular-devkit/schematics: 0.3.2
- @ngtools/json-schema: 1.2.0
- @ngtools/webpack: 1.10.2
- @schematics/angular: 0.3.2
- @schematics/package-update: 0.3.2
- typescript-fsa-reducers: 0.4.5
- typescript-fsa: 2.5.0
- typescript: 2.6.2
- webpack: 3.11.0

什么不再起作用？

++运算符不累加：

 let index = 1;
 console.log(index++) //still 1
 console.log(index + 1) //index = 2, ok.

没有引发异常。

Document.open上的GeneralException：

 return Word.run(async context => {
        const doc = context.application.createDocument(myBase64String);
        context.trackedObjects.add(doc);
        context.load(doc);
        doc.load('contentControls/items');

        return context.sync().then(() => {
          return doc;
        });
 });

Visual Studio输出（附加到iexplore-Process）：
