R Leaflet legends are centered when labelled as `fig-`s

Bug description

When a leaflet map is included in a Quarto HTML report, any categorical legend ends up centered when the chunk is labelled as a figure. This looks a little strange/ugly, particularly when the labels are either very different lengths or are only subtly different lengths. Oddly, if you just print the leaflet map without labelling it as a figure, everything works okay.

Note that you can manually fix this by adding this to a style tag, but I imagine this isn't the intended fix, and that messing around with quarto's style options may have unintended consequences.

.quarto-figure-center>figure>p, .quarto-figure-center>figure>div {
    text-align: left;
}

No idea if this happens with Python/Folium, but I intuitively expect so?

Steps to reproduce

---
title: Dodgy leaflet
format: html
---

```{r}
#| label: makemap
library(leaflet)

map <-
  leaflet() |> 
  addTiles() |> 
  addLegend(
    labels = c("Big long label oh no!", "lil' lab"), 
    colors = c("red", "blue")
  )
```


```{r}
#| label: fig-leaflet
#| fig-cap: "A leaflet figure"
map
```

```{r}
#| label: nolab
map
```

Expected behavior

The leaflet legend should be left aligned (bottom of image).

Actual behavior

The leaflet legend is centered (top of image).
