Quarto revealjs ignores global fig-align and fig-asp settings when rendering plots.

Bug description

I'm trying to set global values for fig-align and fig-asp in a revealjs presentation, but quarto is ignoring them. I've tried setting them in the top level yaml (as in the example below), within execute: and within format: revealjs:, but the behavior is the same in each case. Unlike fig-asp and fig-align, quarto does respect a global setting of fig-dpi.

Steps to reproduce

---
title: "Presentation Title"
format: 
  revealjs:
    width: 1500
    height: 900
    margin: 0.1
fig-align: center
fig-asp: 1
fig-dpi: 600
editor: source
---

```{r include=FALSE}
library(tidyverse)
```

```{r}
p = iris %>% 
  ggplot(aes(Petal.Length, Petal.Width, colour=Species)) + 
  geom_line() +
  geom_point()
```

## Title

Ignores `fig-asp` and `fig-align`, regardless of whether these are in top-level yaml, within `execute:` or within `revealjs:`. 

```{r}
p
```

## Title

With a `label` added to chunk options: Respects `fig-align`, but ignores `fig-asp`. But now there's an unwanted `Figure 1` added as a caption.

```{r}
#| label: fig-1
p
```

## Title

Respects local `fig-asp` and `fig-align`.

```{r}
#| fig-asp: !expr 9/10
#| fig-align: center
p
```

Output:

Expected behavior

All plots should be rendered using the global fig-align and fig-asp values set in the yaml, unless overridden by local settings in a given chunk.

Actual behavior

• In a chunk without a label, quarto ignores global fig-align and fig-asp.
• In a chunk with a label, quarto respects global fig-align and ignores global fig-asp, but adds an undesired Figure 1 caption below figure.
• quarto respects fig-align and fig-asp when set locally within a chunk.

Use the supplied R revealjs presentation as the reproduction case, checking the output for global fig-align and fig-asp settings with and without a chunk label. Trace the revealjs rendering path for these global figure options; done means both settings apply globally without requiring local chunk options or adding an unwanted Figure caption.
