No hover effects in new Interactive UI

No hover effects in new interactive UI when using pandas’ MultiIndex. Example:

import pandas as pd

url = 'https://api.census.gov/data/2018/acs/acs5/groups/B11002.html'
df = pd.read_html(url)[0]
df = df[['Label', 'Name']]

# only keep Estimate variables
df = df[df.Name.str.endswith('E')]

# make levels
df_level = df.Label.str.split('!!', expand=True).fillna('')
idx = pd.MultiIndex.from_frame(df_level)

# add levels to api variable name
df[['Name']].set_index(idx)

@StevenLi-DS Thanks for the report here and the clear repro. I repro the same thing. Just something we lost in the transition to the new UI. We’ll look into it.
