When trying to render the Vaadin-based Geographical maps with the Chrome browers, the page hands at the loading dial and the console shows:
Refused to display 'https://maps.google.com/maps/api/js?sensor=false' in a frame because it set 'X-Frame-Options' to 'sameorigin'
We currently try to pull in this asset, but it does not appear to be used.
23.0.3 and 23.0.4 are confirmed to be affected. 24.0.0 which uses a newer version of Vaadin does not appear to be affected.
