How can I print tibbles when chunk is run in R Notebook in RStudio?

Question

I cannot print a Tibble created by the CSV file below by running a chunk in an R Notebook in RStudio. The following example prints messages about parsing from read_csv but does not print df. However, when I preview the notebook, the data frame is printed. The data frame is also printed when entering the code using the R console.

---
title: "Min Example"
output: html_notebook
---

```{r chunk}
library(readr)
library(tibble)
df <- read_csv('min.csv')
df
```

The command head(df) also produces no output when the chunk is run, but summary(df) and str(df) do produce output in the notebook.

I am using the latest version of RStudio, 1.0.136, and my packages are up to date. My session info follows

The contents of the CSV file are

I might have faced a similar problem, and did solve it by installing the 1.1.89 Version available here.
