Tests are passing. I think the change is small enough it is worth backporting.

@cscheid adding you as review to valide backport or not.

# Hello World

```{python}
#| label: fig-polar
#| fig-cap: "A line plot on a polar axis"

import numpy as np
import matplotlib.pyplot as plt

r = np.arange(0, 2, 0.01)
theta = 2 * np.pi * r
fig, ax = plt.subplots(subplot_kw={'projection': 'polar'})
ax.plot(theta, r)
ax.set_rticks([0.5, 1, 1.5, 2])
ax.grid(True)
plt.show()
```

we do get

#figure([
#box(image("index_files/figure-typst/fig-polar-output-1.svg"))
]
