showLayerInfoPopup shows empty popup when clicking beside feature

[PitWenkin]

When using showLayerInfoPopup: true clicking anywhere on the map where no feature exists results in an empty popup e.g. https://apiv4.geoportail.lu/proj/1.0/build/apidoc/examples/#example14

This only happens when adding at least one layer. When using MyMaps with custom click event, an empty popup is opened in addition to the popup generated by the custom click event.

This is solved in apiv4

Seems not to be fixed when having multiple layer enabled. Or depends ot the selected layers.

I have added the following layers to my map and they are enabled:

• Chantiers actuels (pistes cyclables nationales)
• Bornes Chargy
• Pistes cyclables nationales
• chantiers actuels (CITA)
• mBox
• Transport en commun - Arrêts

When clicking anywhere on the map the request

is triggered and returns

[{"remote_template": false, "template": "bus.html", "layer": "147", "ordered": false, "features": [], "has_profile": false, "total_features_count": 0, "features_count": 0, "tooltip": ""}, {"remote_template": false, "template": "default.html", "layer": "682", "ordered": false, "features": [], "has_profile": false, "total_features_count": 0, "features_count": 0, "tooltip": "\n"}, {"remote_template": false, "template": "default.html", "layer": "685", "ordered": false, "features": [], "has_profile": false, "total_features_count": 0, "features_count": 0, "tooltip": "\n"}, {"remote_template": false, "template": "default.html", "layer": "808", "ordered": false, "features": [], "has_profile": true, "total_features_count": 0, "features_count": 0, "tooltip": "\n"}, {"remote_template": false, "template": "default_table.html", "layer": "1381", "ordered": false, "features": [], "has_profile": false, "total_features_count": 0, "features_count": 0, "tooltip": "\n"}, {"remote_template": false, "template": "default.html", "layer": "1713", "ordered": false, "features": [], "has_profile": false, "total_features_count": 0, "features_count": 0, "tooltip": "\n"}]

All Layers except the Bus layer return \n in their tooltip which results in a popup with 4 hr's. https://github.com/Geoportail-Luxembourg/geoportailv3/blob/45722f46bd5e4650ed3b01b1920de3732f848186/geoportal/jsapi/src/map.js#L2639

Maybe the return should not be simply \n or \n should also be considered as an empty return. https://github.com/Geoportail-Luxembourg/geoportailv3/blob/45722f46bd5e4650ed3b01b1920de3732f848186/geoportal/jsapi/src/map.js#L2713

Seems to be fixed at a first glance. I will check in detail next week.
