Cannot get LabelSet to work with hbar plot

I’m trying to use LabelSet with hbar plot, but the labels are not displaying. What am I doing wrong?

from bokeh.plotting import figure
from bokeh.models import ColumnDataSource, LabelSet
from bokeh.plotting import curdoc

y = ['cat1', 'cat2', 'cat3', 'cat4']  


source = ColumnDataSource(
    data = {
        'y': y,
        'right': [30,40,20,70],
        'right_labels': ['30%', '40%', '20%', '70%']
    }
)
fig = figure(
    x_range=[0,100],
    y_range=y,
)

fig.hbar(
    y='y',
    left=0,
    right='right',
    height=.5,
    source=source,
)

labels = LabelSet(                                                                                            
    y='y',
    x='right',
    text='right_labels',
    source=source,
)
fig.add_layout(labels)

curdoc().add_root(fig)

According to the topmost reply in this stackoverflow topic and the github issue it references, labels with categorical data do not work.

https://github.com/bokeh/bokeh/issues/7141

The github issue is still open, so presumably it is still unresolved. Perhaps some of the workarounds in that stackoverflow topic might inspire a workaround solution in the interim.
