I made a quick test, changing the fuel and charging stations to forced. While the stations are visible on zoom 13, they are not visible on zoom 11.

I don't know if this is related to the priorities in the theme or more work is needed? Should we expect the forced to be visible on all zoom levels regardless of priority?

There was an overridden method in PointTextContainer that was forgotten, now fixed, that might change the behavior in your test.

Not sure about zoom levels and priorities. It seems unrealistic that the icon would be visible at all zoom levels. Probably the reader just doesn't load the icon if the zoom-min doesn't match (so the icon never even gets to the element placing / collision detection algorithm).
