HeatmapLayer rendering severely wrong in interleaved Maplibre rendering

Editing from the duckdb example: https://github.com/developmentseed/lonboard/blob/fe4e1f7c34f0dcda347156212d683688675b1e85/examples/duckdb.ipynb

basemap = MaplibreBasemap(mode="interleaved", style=CartoStyle.Positron)
layer = HeatmapLayer.from_duckdb(con.table("rides"), con, before_id="watername_ocean")
m = Map(layer, height=700, basemap=basemap)
m

Everything looks fine in overlaid mode:

m = Map(layer, height=700, basemap=MaplibreBasemap(mode="overlaid", style=CartoStyle.Positron))
m
