multiple annotations appear to be malfunctioning

[romunov]

When researching for this question I noticed that example on Text and annotations page is not working for me.

a <- list()
for (i in seq_len(nrow(mtcars))) {
  m <- mtcars[i, ]
  a[[i]] <- list(
    x = m$wt,
    y = m$mpg,
    text = rownames(m),
    xref = "x",
    yref = "y",
    showarrow = TRUE,
    arrowhead = 7,
    ax = 20,
    ay = -40
  )
}

plot_ly(mtcars, x = ~wt, y = ~mpg) %>%
  add_markers() %>%
  layout(annotations = a)

There is no plot (using RStudio) and if I save the (empty) png image, it's 800 kb of nothing but white.

Another interesting thing I noticed is that the plot doesn't render on the site, either. All other plots appear to work flawlessly. Is there something I'm missing?
