Styles not loaded when scrolling without using ctrl

[kreinholt]

Description

When you scroll without using ctrl, an overlay should appear saying "Use ctrl + scroll to zoom the map" as is seen in https://developers.google.com/maps/documentation/javascript/adding-a-google-map.

If you try to scroll without ctrl at https://www.webcomponents.org/element/GoogleWebComponents/google-map, the text appears, but in the top left corner hidden by the Map/Satellite control. Appears gm-style-pbc css is missing.
