Hey,

When visiting [https://www.visitlimburg.be/nl/fietsen-tussen-de-mijnterrils]
(https://www.visitlimburg.be/nl/fietsen-tussen-de-mijnterrils) it not always shows the map properly.
Sometimes it shows the correct place on the OSM map and the other time it shows the world map.

See pictures bellow

The site is using the discription on website bellow

I Think it has somthing to do with cookies, because when I enable Functional cookies it works fine

Have you contacted the website support to make them aware of this issue? You may also link to this thread.
At this point it’s not clear whether this is an OSM issue or a website issue, considering that cookies are the responsibility of the website.

The plain HTML works as expected.
