Is it possible to fix the head for a long html huxtable?

Question

This works for tables produced with kableExtra which is useful when inspecting long tables. I was wondering if anyone has an idea how this may be doable with huxtable.

Here's an example Rmd to get an idea of what I mean. I'd like the huxtable header to be fixed at the top of the page when scrolling down just like in the kable.

```{r lib}
library(magrittr)
```

```{r kable}
iris %>%
  head(20) %>%
  kableExtra::kbl(caption = "a caption") %>%
  kableExtra::kable_styling(fixed_thead = TRUE)
```

```{r huxtable}
iris %>%
  head(33) %>%
  huxtable::hux() %>%
  huxtable::set_caption("a caption")
```

```{=html}

table.huxtable th {
  position: sticky;
  top: 0;
  background: white;
}
