Content Break, Full Width Map

I am using a Content Break shortcode to add a full width area at the top of my page. I am using WP Google Maps to create a custom map that I am displaying in that area. However, although the map is set at 100% width (responsive) I cannot get it to fill the section.

Any insight on how I can get the map to become full screen width as well?

If I use the lead area instead, the map does fill the entire width of the screen, however I lose the functionality of the map and cannot click the map markers anymore.

Best,
Cheri
