Combining `GeoJson` markers in a `MarkerCluster` shows unclustered markers

Please add a code sample or a nbviewer link, copy-pastable if possible

with open('examples/data/search_bars_rome.json') as f:
    data = json.load(f)
data_url = 'https://raw.githubusercontent.com/python-visualization/folium/master/examples/data/search_bars_rome.json'

m = folium.Map((41.9, 12.5), tiles='cartodbpositron')
marker_cluster = folium.plugins.MarkerCluster(name='mc').add_to(m)
folium.GeoJson(data_url, embed=False).add_to(marker_cluster)
folium.GeoJson(data_url, embed=False, name='geojson').add_to(m)
folium.LayerControl(collapsed=False).add_to(m)
m.save('_map.html')
m

Problem description

I expected to see the markers in a clustered fashion

I can’t tell from #1190, #1129 and #1188 if this is fixed in version 0.10.0, and if it is, what’s the right syntax?

Expected Output

Clustered markers (This was taken from another example)

Output of folium.__version__

‘0.10.0’

The fix has been merged. It will be in the next release, v0.12.0, release date yet unknown. If you want it earlier you can install folium from the main branch:

pip install git+https://github.com/python-visualization/folium.git@master

It seems combining GeoJsonTooltip and MarkerCluster plugin is not supported behavior. Note that while everything in the base folium library should work well together we can’t guarantee that for the plugins.

I don’t think using the FeatureGroupSubGroup plugin is a real solution here. I’ll make a PR where we do the ajax call asynchronously.
