Raster tile sources have no way to limit tile requests to their real extent
Unlike the other
mapStyletypes, an OpenLayerstype: 'raster'(plain XYZ) source has no extent set on itsTileGrid. This means tile requests can be made anywhere across the whole tile grid, not just where the tile service actually has coverage — leading to 404s in the console whenever the map is panned or zoomed into an area outside the service's real extent.Fix
Adds an optional
extentproperty tomapStyleconfig, passed through to the OpenLayersTileGridto constrain which tiles get requested. It only affects which tiles are requested — panning and zooming are unaffected, so users can still move outside the extent (they'll just see the background colour instead of failed requests).This is opt-in and backwards compatible: omitting
extentkeeps today's behaviour unchanged. There's no discovery protocol for a bare XYZ tile URL to determine its own coverage, so this has to be supplied explicitly by whoever configures the style.
