Map displays wrong icons if a request is made to a new tileServerUrl within 50-60sec of the first request

[pratikmdhr]

When the first request is made to  tileServerUrl: https://{s}.treetracker.org/tiles/ , the map shows correct icons with no problems. Now if a second request is made to a new tileServerUrl tileServerUrl: https://{s}.treetracker.org/tiles/new/ within 50-60 seconds of the first request, the map will still show the old icons. If zoomed in, the map may display the correct new icons (but not always)...

If a new request is made after 1min, the map shows correct icons with no problems
