Hi,

I am trying to use google-map element with Angular 2: the display is correct, and all the google-map properties work well, but the properties of google-maps-api. For example:

<google-map api-key="AIzaSyCqrVHpM_zlUEPtxJPQiFYIqwfKcOctB_M" language="en" latitude="37.77493" longitude="-122.41942"></google-map>

I see the following error twice, once for each property that belongs to the google-maps-api (language and api-key):

You have included the Google Maps API multiple times on this page. This may cause unexpected errors.

In fact, in the browser Sources, I see three loads of Google Maps Api: one with no parameters, one with the API key and finally one with the API key and the language.

If I set directly into the google-map the properties, the error does not occur:

<google-maps-api id="api" api-key="AIzaSyCqrVHpM_zlUEPtxJPQiFYIqwfKcOctB_M" client-id="[[clientId]]" version="[[version]]" signed-in="[[signedIn]]" language="en" on-api-load="_mapApiLoaded"></google-maps-api>

I have seen that this error occurs in other cases, such as: #22

Is there an explanation? Thanks.
