Here is the big part @jieter but there's still a lot of work to fix preview page, and i'm not sure to have motivation to upgrade all vendor script :\

Another options would be to point demo page to https://leaflet-extras.github.io/leaflet-providers/ and wait for someone to upgrade preview page or ditch it if we don't have energy to do it.
