### Bug description

Hi,
I have the code below.

If I try to render it, the altair chart is not rendered.

If I remove the OJS table the chart is rendered.

In the browser console I have these vega errors:

I'm using quarto 1.3.19 in debian 11.

Thank you

## OJS

```{ojs}
//| echo: false
data = FileAttachment("tmp-ojs.csv").csv({ typed: true })
Inputs.table(data)
```

## altair

```{python}
#| echo: false
import pandas as pd
import altair as alt

df = pd.read_csv("tmp.csv",keep_default_na=False)

df['year'] = pd.to_datetime(df['year'], format='%Y')

alt.Chart(df).mark_area().encode(
    alt.X('year:T', timeUnit = 'year',title='year',axis=alt.Axis(tickCount='year')),
    alt.Y('v:Q',axis=alt.Axis(format='%'),title='percentage'),
    color='i:N'
)
```
