Map initialization not correctly centered when displaying an element with large boundaries

[dtrucs]

Since 3.23.0 version and its upgrade of a numerous packages related to leaflet there is a regression concerning large lineString not correctly centered once the page loads. It appears zoomed in.

After some investigations:

• The map container have not minZoom explicitly defined
• If we define an explicit 0 value, the bug is gone.
• According to the leaflet documentation:

  If [the minZoom is] not specified and at least one GridLayer or TileLayer is in the map, the lowest of their minZoom options will be used instead.

• But we don't want to define it explicitly because we let the user to choose minZoom / maxZoom by defining in the options of tileLayer in map.json.
• There is no minZoom specified, but it seems curiously to be set to 13. And it looks like a matching with default value of zoomAvailableOffline settings.

Identified here, the load of mapOfflineLayer forces a minZoom to 13.

Fixed since 3.24.2.
