ALL software version info
Online nyc_buildings notebook ((https://nyc-buildings-notebook.pyviz.demo.anaconda.com/notebooks/nyc_buildings.ipynb#))
Tested with Chrome
Description of expected behavior and the observed behavior
The legend should be shown only once, and deselecting a type of building should hide it what doesn't happen.
Complete, minimal, self-contained example code that reproduces the issue
All code is online
polys = hv.Polygons(ddf, vdims='type')
shaded = datashade(polys, color_key=color_key, aggregator=ds.by('type', ds.any()))
hover = inspect_polygons(shaded).opts(fill_color='red', tools=['hover'])
tiles * shaded * legend * hover
Screenshots or screencasts of the bug in action

Actual behavior :
As I manage to reproduce the same behavior locally, what would be the correction to make?
