BoxWhisker: outliers are not displayed on bokeh backend

[alxthm]

ALL software version info

Python: Python 3.9.17
Relevant requirements:

bokeh==3.4.0
holoviews==1.18.3
matplotlib==3.8.3

Browser: firefox 124.0.1 (64-bit), macOS

Description of expected behavior and the observed behavior

On bokeh backend, the BoxWhisker plot does not display outliers (normally rendered as dots or circles, outside the box limits).

The plot does work as expected on a matplotlib backend.

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

import holoviews as hv
import numpy as np

x = np.random.randn(1000)
print(max(x)) # prints `2.8981705376936917` in this example

# here, outliers are displayed as expected (see screenshots)
hv.extension('matplotlib')
hv.BoxWhisker(x, vdims='Value')

# here, no outliers are displayed
hv.extension('bokeh')
hv.BoxWhisker(x, vdims='Value')

Stack traceback and/or browser JavaScript console output

Looking at the browser console, this warning appears each time I try to plot a BoxWhisker:

[bokeh 3.4.0] attempted to retrieve property array for nonexistent field 'radius'
