Rmarkdown beamer ignoring size option

I'm trying to create a presentation with Rmarkdown and beamer and I am unable to adjust the size of my code and output. In the past I edited the beamer template to work around this but I was hoping there is a better way.

For example:

---
title: "Reprex"
output:
  beamer_presentation
---

## Output one

```{r, size="footnotesize"}
1:50
```

renders identical to:

---
title: "Reprex"
output:
  beamer_presentation
---

## Output one

```{r}
1:50
```

Any thoughts on how to fix this?

The size option specifies the "font size for the default LaTeX output" (source). But you are writing rmarkdown which is converted to PDF afterwards.

A workaround:

---
output: beamer_presentation 
---

## Output one

Foo.

```{r, echo = FALSE}
knitr::asis_output("\\footnotesize")
1:10 # this will be small
knitr::asis_output("\\normalsize")
11:20 # this not
```

Bar.

Depending on how often this is used it could be work using a helper function or even a chunk hook to print the font size commands.
