Advanced mode: WARNING - mismatch of the addEventListener property on type Window

Compiling in advanced mode
```
compilerOptions.setLanguageIn(LanguageMode.ECMASCRIPT_NEXT);
compilerOptions.setLanguageOut(LanguageMode.ECMASCRIPT5);
```

I receive a lots of this warnings:
```

In my code I have something like `htmlElement.addEventListener("click",()=>{})`
I also call addEventListener from window object. Hope this helps.

I'm using v20190415.
