Interactive rmarkdown document does not display correctly after browser update

Question

I run the following interactive rmarkdown document:

### Example of shiny app ```{r, echo = FALSE, eval = TRUE} numericInput("rows", "How many cars?", 5) renderTable({ head(cars, input$rows) }) ``` ### Another example ```{r, echo = FALSE} sliderInput("bins", "Number of bins:", min = 1, max = 50, value = 30) renderPlot({ x <- faithful[, 2] # Old Faithful Geyser data bins <- seq(min(x), max(x), length.out = input$bins + 1) # draw the histogram with the specified number of bins hist(x, breaks = bins, col = 'darkgray', border = 'white') }) ``` 

saved as minimal .Rmd, I launched it by running

 rmarkdown::run("minimal.Rmd") 

on the R console. After executing this document, the document displays correctly in the browser:

After updating the browser, the document looks as follows:

(I tried this on chrome and safari)

I noticed that when I run rmarkdown :: run right after saving the .Rmd file, I get a knitr-like output in the R console, and the document displays correctly; when rmarkdown :: run is run without saving the file again, the output on the console is not displayed, and the document is not displayed correctly. This may be due to rmarkdown :: run caching. I get: "
