Can't render map in storybook

[tpliakas]

Hello all.

I have a working map component and tried to add it to storybook. I get errors like
Unknown custom element <GmapMap>
Unknown custom element <GmapMarker>
Unknown custom element <GmapInfoWindow>.
Tried to add different imports inside the story file but I couldn't get it to work and also had a look at #437

Does anyone have any idea on what to do in my story file to render the map?
