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

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.

---output: bookdown::html_document2---```{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")```
