Why column: margin doesn't work with renderings: [light, dark]?

[tentacles-from-outer-space]

Description

Is it known issue that this options doesn't work together? Is it related to cell cross-reference with renderings option? Or I am missing something?

---
title: "Untitled"
format:
  html:
    theme:
      light: flatly
      dark: darkly
---

```{r}
table_light <- data.frame(x = "I am light mode table", y=1)
table_dark <- data.frame(x = "DARK MODE", y=2)
```

# dark/light mode - works

```{r}
#| renderings: [light, dark]

knitr::kable(table_light)
knitr::kable(table_dark)
```

# to the Margin - works

```{r}
#| column: margin

knitr::kable(table_light)
knitr::kable(table_dark)
```

# both together - not work

```{r}
#| column: margin
#| renderings: [light, dark]

knitr::kable(table_light)
knitr::kable(table_dark)
```

# with explicit div - works

::: {.column-margin}

```{r}
#| renderings: [light, dark]

knitr::kable(table_light)
knitr::kable(table_dark)
```

I can reproduce this, and I think this is a conflict in how cell renderings works.

Using the Div syntax is the right way to do it currently; I'll open an issue to see if we can improve.
