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))

首先，使用 iris、plot_ly、boxpoints="all" 以及映射到 Petal.Width_high 的 symbol 重现所提供的 R 示例。调查 symbol 映射为何会拆分第三个箱线图，并在每个箱中渲染不同的点符号且不改变箱的分组后，认为该 issue 已完成。
