Add new functionality to v4: embedded mode (just add param ?embedded=true in url)
Force resize map when embedded mode, with a timer for v3 (because of angular component, wait until they have finish rendering header and footer that will disappear, otherwise, there is an unwanted gutter). For v4, no timer needed.
