Description of expected behavior and the observed behavior

holoviews.operation.datashader.inspect_points allows inspecting all vdims in DynamicMap. But when using it with gv.Points, points disappear as soon as the mouse enters the frame. holoviews.Points don't have this issue.

This issue was first found here: https://discourse.holoviz.org/t/one-dimension-missing-on-hover-after-rasterize-point-data/4049

Complete, minimal, self-contained example code that reproduces the issue

import numpy as np
import pandas as pd
#import holoviews as hv
import geoviews as gv
#hv.extension('bokeh')
gv.extension('bokeh')
import holoviews.operation.datashader as hd

lon = np.array([8.75,8.76,8.77])
lat = np.array([46.1,46.2,46.3])
height = np.array([0.0,0.1,0.2])
index = np.array([0,1,2])

df = pd.DataFrame(dict(Longitude=lon,Latitude=lat,Height=height,Index=index))

gvpoints = gv.Points(df, ['Longitude','Latitude'])
#hvpoints = hv.Points(df, ['Longitude', 'Latitude'])

rasterized = hd.dynspread(hd.rasterize(gvpoints).opts(width=300, height=300))
highlight= hd.inspect_points(rasterized)
rasterized * highlight.opts(marker='o',size=10,tools=['hover'])
