add_annotations() seems to ignore font properties

[dichika]

Hi,
add_annotations() seems to ignore the font properties(e.g. color, size).

library("plotly")
plot_ly(values=c(1,0), type="pie") %>% 
  add_annotations(text = "TEST",
                  font=list(color="white")
  )

Here is my sessionInfo().
