Wrap around the date line in the map causes position issues

[lukasrad02]

When placing features in the map and then wrapping around the date line, OpenLayers shows the feature in the "second word", too (with the exception of the delete feature (trash bin) which disappears). However, the coordinates will be different.

Therefore, popups still show next to the "original" feature and might not be visible to the user.

The two flames in this image are the same feature. Dragging and moving one of the flames moves the second one, too.

When clicking any of the two flames, the popup always shows in this location and might be out of the viewport for higher zoom levels.

Since exercises are unlikely to span an area crossing the date line, it should be enough to prevent wrap around in OpenLayers completely.

I knew you would work on larger exercises and scenarios, but I didn't imagine they would get as big as in these pictures XD
