Failure to overlay text on bar chart.
ALL software version info
Python 3.10.6 hvplot==0.8.3 holoviews==1.15.4 bokeh==2.4.3 jupyterlab==3.6.3
Description of expected behavior and the observed behavior
Should be able to add text to a bar chart as described here: https://stackoverflow.com/questions/46223037/add-text-annotations-to-each-data-point-in-holoviews-plot
Complete, minimal, self-contained example code that reproduces the issue
import pandas as pd
import hvplot.pandas
import holoviews as hv
df = pd.DataFrame([[1,2,3,4,5]])
df.hvplot.bar() * hv.HLine(df[0].mean()) * hv.Text(1, df[0].mean(), "Mean")

I can reproduce it with the code given above.
Only plotting the bar returns this:
Where all bars are plotted over each other. Transposing the DataFrame gives a more desirable look:
Which is able to be used with hv.Text:
I'm getting a similar problem in a different situation when trying to compose two bar plots using + operator.

import holoviews as hv
df = pd.DataFrame([[1,2,3,4,5],[1,2,3,4,5]])
df.hvplot.bar(y=['0','1']).opts(multi_level=False) + df.hvplot.bar(y='0')
Looking at the error, I can see it happens in Panel, so the fix maybe be needed there. As a work-around for now you can
import pandas as pd
import hvplot.pandas
import holoviews as hv
df = pd.DataFrame([[1,2,3,4,5],[1,2,3,4,5]])
(df.hvplot.bar(y=['0','1']).opts(multi_level=False) + df.hvplot.bar(y='0')).opts(shared_axes=False)
