Chunk options with Julia engine

[AdaemmerP]

Description

When using the Julia engine with quarto, certain chunk options, as with knitr, are not working. For example, centering a plot or changing its width are not working as it remains left-aligned:

```{julia}
#| echo: false
#| fig-width: 12
#| fig-align: center
using Plots
x = collect(1:50)
y = randn(50)
plot(x, y)

Is there an overview what chunk options are supported with the Julia engine?
