plotly problem of specifying point symbol within the boxplot

Hi I am trying to specify the point symbol (shape) based on a factor, so that the point shape within the boxplot can be different (which can be very useful for highlighting a group of points). However, it looks like instead of showing different shapes, the third boxplot got split into two boxes.

Can you please advise how to achieve that?

Brief description of the problem

library(dplyr)
data(iris)
iris=mutate(iris, Petal.Width_high=ifelse(Petal.Width>2,"High","Low"))

iris %>% plot_ly(x = ~ Species, y = ~ Petal.Width, color= ~ Species,
                 symbol = ~ Petal.Width_high,
                 type = "box", mode="markers",boxpoints="all",
                 jitter = 0.4, marker = list(size = 10),
                 pointpos = 0,hoverinfo='text',
                 text= ~paste('</br>Species: ', Species,
                              '</br>Petal.Width: ', Petal.Width))

Beginne damit, das bereitgestellte R-Beispiel mit iris, plot_ly, boxpoints="all" und auf Petal.Width_high abgebildetem symbol nachzustellen. Untersuche, warum die symbol-Zuordnung den dritten Boxplot aufteilt, und betrachte das Issue als abgeschlossen, wenn innerhalb jeder Box unterschiedliche Punktsymbole gerendert werden, ohne die Gruppierung der Boxen zu ändern.
