Bar chart between two dates is not showing when using vegafusion

[samesand]

What happened?

I'm trying to plot a the following Pandas Dataframe, using alt.data_transformers.enable('vegafusion'):

test_data = pd.DataFrame([{'entity':1, 'start_time':pd.to_datetime('2024-11-03 00:15:00'), 'end_time':pd.to_datetime('2024-11-03 01:02:00')}])
alt.Chart(test_data).mark_bar().encode(x='start_time', x2='end_time', y='entity')

This returns and empty chart, and it only plots the data if the start_time is greater than 2AM.

If I don't enable vegafusion, the chart displays correctly.

What would you like to happen instead?

The chart show show a bar between the two time stamps
