Simple bar chart in Holoviews breaks when I create Dynamic Object out of it

Question

This is my code, it works bar for last line (commented out)

#imports
import pandas as pd
import numpy as np
import holoviews as hv

# loading holoviews engine
hv.extension('matplotlib') #('bokeh')

# creating dummy data
samples = 1000
countries_sample = np.random.choice(['GBR', 'ITA'], samples)
hours_sample = np.random.choice(list(range(0,23)), samples)
count = np.random.randint(1, 5, size=samples)

df_test = pd.DataFrame({'location_country_iso3': countries_sample, 'hour': hours_sample, 'Count': count})
df_test = df_test.groupby(['location_country_iso3', 'hour']).size() 

# function to draw output
def draw_bars(country):
    return hv.Bars(df_test
                  ).sort().select(location_country_iso3 = country)

# dynamic map out of the function, to select single country
dmap_bars = hv.DynamicMap(draw_bars, kdims = ['country'])

# specific country selection
dmap_bars['GBR']

## options for country selection (this breaks):
# dmap_bars.redim.values(country = ['GBR', 'ITA'])

The above code creates bar chart as intended, for the selected country:

However, when I introduce options for the Dynamic Map object:

# options for country selection (this breaks):
dmap_bars.redim.values(country = ['GBR', 'ITA'])

The code breaks. Dynamic Map does not receive the required selection, while error message is completely unrelated and unhelpful. Error message is also different running on 'Bokeh' / 'Matplotlib' engines, below is for when running on 'Matplotlib':

Reinstalled fresh environment.

Tried recreating dummy data.

Tried moving various parts of the slicing (selection) process within draw_bars() function, using native hv.Dataset object to execute the slicing. Absolutely no difference.
