Please, consider the following quarto document. The figure is not being centered. Am I doing something wrong? Thanks!

format: typst
jupyter: python3

```{python}
#| echo: false
#| fig-align: center

import matplotlib.pyplot as plt
import numpy as np

# Data for plotting
t = np.arange(0.0, 2.0, 0.01)
s = 1 + np.sin(2 * np.pi * t)

fig, ax = plt.subplots()
ax.plot(t, s)

ax.set(xlabel='time (s)', ylabel='voltage (mV)',
       title='About as simple as it gets, folks')
ax.grid()

plt.show()
```
