ggplotly with facet_grid creates copies of legend items

[royr2]

Hi @cpsievert
Is there any way to let each trace remain associated with the same legend item (as opposed to having a new legend item for each plot)? Just the way ggplot2 does it?

thanks !

library(plotly)
library(reshape2)

ds <- data.frame(X = 1:100, 
                 Y1 = rnorm(100), 
                 Y2 = rnorm(100), 
                 group = LETTERS[1:4])

ds <- melt(ds, id = c("X", "group"))

ggplot(ds, aes(X, value)) + 
  geom_point(aes(color = group)) +
  facet_wrap(~variable)
ggplotly()

ggplot:
