Bug: Colorbar duplicated when specifying color and symbol in marker argument

Whenever I plot a 3d scatter with color and symbol, the colorbar seems to be duplicated. This issue does not occur when symbol is removed so I believe it is an issue with the combination of the two.

library(tidyverse)
mtcars <- mtcars %>% mutate(make = substr(word(rownames(mtcars), 1), 1, 1), model = word(rownames(mtcars), 2))
pca <- PCAtools::pca(t(mtcars[,c(1:4)]), metadata = mtcars[,c("carb","gear","qsec", "make", "model")])
p <- plot_ly(data = pca$rotated, 
             x = ~PC1, y = ~PC2, z = ~PC3,
             height = 600,
             marker = list(color = pca$metadata$qsec,
                           colorscale = "Jet",
                           colorbar = list(title = "Test",
                                           y = 0.5, x = 0, len = 0.5)),
             symbol = pca$metadata$make)

Reproduisez l’exemple fourni de plot_ly 3D scatter avec marker color et symbol, puis examinez la gestion par plot_ly des options marker et colorbar. Comparez-le avec la version qui omet symbol. C’est terminé lorsque l’exemple affiche une colorbar avec le titre et le positionnement demandés.
