Downsample on target with RangeToolLink prevents display of data if zoomed and then rangetool-panned

ALL software version info

(this library, plus any other relevant software, e.g. bokeh, python, notebook, OS, browser, etc)

Description of expected behavior and the observed behavior

If you zoom in to the target plot with wheelzoom, and then try to move the rangetool box around in source plot, the data is not refreshed in the target plot.

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

import pandas as pd
import numpy as np
import hvplot.pandas
from holoviews.plotting.links import RangeToolLink

n_samples = 1000
data = np.random.randn(n_samples)

df = pd.DataFrame({'time': np.arange(len(data)), 'value': data})
plot = df.hvplot(x="time", y="value", height=500, downsample=True)
minimap = df.hvplot(x="time", y="value", height=150)
link = RangeToolLink(minimap, plot, axes=["x", "y"])

(plot + minimap).opts(shared_axes=False).cols(1)

This issue of missing data is resolved by https://github.com/bokeh/bokeh/pull/13603. But it looks like downsampling may not be working.
