Adding WFS service to map from metadata record not working

[mbrunger]

Adding WFS services to the map using the 'Add to map' button from a metadata record does not work. The WFS is added to the map as a layer but does not appear on the map. The problem seems to be that 'version=undefined' is automatically added to the request in all cases, even when a specific version is written in the metadata record link.

Steps to reproduce the behavior:

1. Create a new metadata record using the general iso19115-3.2018 metadata scheme or the Dutch iso19139.nl.geografie.2.0.0 metadata scheme.
2. Add a link to a WFS service. I tried several options with and without version (see screenshot):

• https://geodata.zuid-holland.nl/geoserver/landelijk_gebied/wfs?service=WFS&version=2.0.0&request=GetCapabilities
• https://geodata.zuid-holland.nl/geoserver/landelijk_gebied/wfs?service=WFS&version=1.1.0&request=GetCapabilities
• https://geodata.zuid-holland.nl/geoserver/landelijk_gebied/wfs?

3. Open the newly added record and click on the 'Add to map' button next to the WFS service link .
4. The WFS service is added to the map as a layer but nothing is shown on the map.

Test environments:

GeoNetwork 3.12.11 server installation with iso19139.nl.geografie.2.0.0 metadata scheme opened with Chrome on Windows
GeoNetwork 3.12.10 Docker installation with iso19115-3.2018 metadata scheme opened with Safari on Mac OSX
