📚 Description

<ScriptMapLibreAttributionControl> found the map's default attribution control by reading map._controls. The field shows up in MapLibre's .d.ts, but nothing promises it stays. If a release renames it, attribution shows twice or fails to come back on unmount, and OpenFreeMap and OpenStreetMap require it to be visible.

MapLibre has no public way to get the default control: the constructor creates it and keeps no public reference. So <ScriptMapLibreMap> now creates that control itself, with the same options, and shares it through the map context. The attribution component swaps it with hasControl, removeControl and addControl. It also listens for the remove event, so it no longer reads _removed.

Behaviour change: the component replaces only the map default. An attribution control added by your own code with map.addControl() now stays, so attribution can show twice, but it never disappears. The docs say so.

Open question: if maplibreLogo is on and logoPosition is bottom-right, the logo and the default attribution swap vertical order in that corner, because the default control is added after the constructor. I left it. Say if it matters.

Checked by hand, since CI cannot show it:

  • I disabled the restore call in the attribution component and rebuilt. The new real-browser test failed with expected [] to deeply equal [ { …(2) } ], so it catches lost attribution.
  • The updated runtime tests hide the fake map's control list. On main they fail with TypeError: Cannot read properties of undefined (reading 'filter'), which is the renamed _controls case.

📝 Walkthrough

Walkthrough

ScriptMapLibreMap now creates and provides one component-managed default attribution control. ScriptMapLibreAttributionControl replaces only that control and restores it through public MapLibre APIs, including map-removal handling. Tests cover control ownership, lifecycle, options, errors, and rendered attribution behavior. Documentation states that separately added attribution controls remain unchanged.

The attribution control found the map default by reading `map._controls`.
A MapLibre release can rename that field. The component would then show
attribution twice, or fail to restore required attribution on unmount.

`<ScriptMapLibreMap>` now adds the default attribution control itself and
shares the instance through the map context. The attribution component
removes and restores that instance with `hasControl`, `removeControl` and
`addControl`, and tracks map removal with the public `remove` event.

Attribution controls that consumer code adds are no longer removed.
