The place pins visibly swam back and forth while the map was dragged and only settled onto their real position when it stopped. The clustered bubbles never did, and that is the clue: those are drawn inside the canvas, the pins are HTML. A library Marker repositions itself on the map's 'move' event, which fires once per pointer sample, while the canvas is redrawn once per animation frame. When the style is heavy or tiles are still streaming, the pins therefore run ahead of the map they are supposed to be pinned to. They now live in their own layer inside the canvas container and are positioned from the map's own 'render' event, so pin and map move on the same clock. Mapbox keeps the library marker: its terrain path needs the altitude handling that comes with it, and the drift was never reported there. Clicks, hover and dragging a pin onto a day are untouched — they hang off the element, which is the same element as before.
