lonboard v0.4.0 polyogn visualization bug

[giswqs]

I tried to render a polygon. GeoPandas can render it properly. However, lonboard seems getting some weird edge rendering issue. Not sure if this a lonboard issue or the deck.gl JS library issue.

import geopandas as gpd
from lonboard import viz

# Downloaded from 'https://data.source.coop/giswqs/nwi/state_boundary/AR.parquet'
gdf = gpd.read_parquet('AR.parquet')
gdf.explore()

viz(gdf, get_fill_color=[0, 0, 255, 128])

It seems this is a new bug introduced in v0.4.0. Downgrading to v0.3.0 solves the issue.
