### Bug description

I'm redoing my website using a Quarto blog. When I have post set to eval: false with a SQL code chunk and an R code chunk, it looks fine. When I remove the R part, it changes formatting.

To reproduce, I have a blog post with each of these options:

1) Blog post without R chunk.

````
---
title: "Test without R"
date: "2022-08-24"
execute: 
  eval: false
---

```{sql test}
SELECT * FROM EXAMPLE;
```

2) Same blog post, but with a blank R chunk at the end.

  eval: false

```{sql test}

```{r}

The SQL section outputs are different.

I don't know why they don't match. I just updated to the newest Quarto version (but I think it was happening on the previous one too). This is on RStudio 2022.07.1 Build 554. "Spotted Wakerobin" for macOS, on Monterey.
