I found raster color legend was changed after subscribing rescale store. Looks like some changes on RasterRescale component will trigger the event in RasterClassifyLegend to change map style.

geohub/sites/geohub/src/components/maplibre/raster/RasterClassifyLegend.svelte

Lines 283 to 287 in 9f9be6b

	if (!layerHasUniqueValues) {
	rescaleStore.subscribe(() => {
	handleRescaleChanged();
	});
	}

this map #192's raster dataset has statistics ranged 0.40465450286865234 to 1.2871990203857422

However, this saved map style is set to 0.36 to 1.4. Because of this difference, it looks like always being updated when correct rescale values is set in editor.

since the latest map with raster looks working well, maybe we can just close this issue...
