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?

Looks like adding a label fixes things:

First, a figure which does *not have a chunk option "label". Despite asking for a center-aligned figure, it is left-aligned. The font of the figure caption is also the same as the text.

#| fig-cap: "Left-aligned figure when it should be center-aligned"
#| fig-width: 12
#| fig-align: center
using Plots
x = collect(1:50)
y = randn(50)
plot(x, y,  size=(250,250))

If we add a "label", then it suddenly becomes center-aligned. Weird.

#| label: fig-center1
#| fig-cap: "Adding a chunk option `label` results in center alignment"
#| fig-width: 12
#| fig-align: center
using Plots
x = collect(1:50)
y = randn(50)
plot(x, y,  size=(250,250))

The font of the figure caption for is also slightly different.

A figure is a cross-referenceable image.
To be a cross-reference, a label with fig- is required.

Are you saying that Quarto should throw an error if a figure doesn't have a label?

[mcanouil]

No.
I'm saying the alignment applies only to "figure" and that figures are cross-reference objects.
