I'm an happy Windows user of skimr 1.0.1. The spark graph (histogram) plot now works nicely:

However, when I combine skim with R Markdown, I lose the ability to show the histograms. According to skimr vignettes, for Markdown output I should combine skim with kable, with a chunk option of results='asis'. I tried the vignette suggestion, as well as kable(skim()) without the chunk option and skim without kable, but none of these prints the histograms:
---
title: "test"
subtitle: "Andrea Panizza"
author: "`r Sys.Date()`"
date: "_reading time: ? minutes_"
output:
html_document:
keep_md: true
fig_caption: yes
params:
output_dir: "../output"

```{r setup, include=FALSE}
library(knitr)
library(skimr)
library(dplyr)
opts_chunk$set(warning = FALSE,
message = FALSE,
echo = FALSE,
fig.align = "center",
fig.width = 7.25,
fig.height = 6)
```
## test 1
```{r}
skim(mtcars)
```
## test 2
```{r}
kable(skim(mtcars))
```
## test 3
```{r, results='asis'}
kable(skim(mtcars))
```
I attach the results as images. You can also recreate them yourself by running my R Markdown example:
As you can see, I can't get the histograms. Am I doing something wrong? Should I open an issue in the skimr repo?
The only other suggestion I have is from the
