Description of expected behavior and the observed behavior

when using pn.bind in a plot, the plot outputs correctly but there is a bokeh validation warning about the sizing mode.

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

import pandas as pd
import panel as pn
import hvplot.pandas # noqa

pn.extension()

df = pd.DataFrame({'x': [1, 2, 3], 'y': [1, 2, 3]})

def plot_data(color='blue'):
    return df.hvplot.scatter(x='x', y='y', color=color)


colors = pn.widgets.Select(options=['red', 'green', 'yellow'])
plot = pn.bind(plot_data, color=colors) # This is what raises the warning
#plot = plot_data() # Does not raise any warning

template = pn.Column(colors, plot)

template.show()
