Is your feature request related to a problem? Please describe.
When visualizing a GeoNode designed embedded map the size of the window in which the map appears sometimes is not large enough to allow a correct visualization of all data represented in the map.

Describe the solution you'd like
Have a button in the embedded map that when clicked that allows to expand it to a full screen visualization, and a button when the map is full screen to reduce the map to its embedded size when clicked again
