Angular 2 Model-Driven form.reset() doesn't reset FormArray property

Question

I have an angular 2 model driven form that has a property of type FormArray. When I call the myForm.reset(this._originalValue) method, the number of items in the FormArray is not reset to the original value.

Here is a plunker showing the problem: https://plnkr.co/edit/gRHD5Ikbm1aGzFQUF2nn?p=preview

Is there a way to force the myForm.reset() method to reset the count of items in properties of type FormArray? Or do I have to manually reset it?

Well, it appears this is a known issue and the Angular team has decided that folks will have to manually reset the FormArray size.
