Ggplotly does not always make a legend correctly for where there are points and lines

Ggplotly does not always make a legend correctly for where there are points and lines. Sometimes it only makes the legend key based on either geom_point or geom_line, whichever is the first layer. Below is an example where it doesn't work. It seems to fix it if the data is arranged by the x variable. It'd be good if it worked for however the data was arranged.

library(dplyr)
library(ggplot2)
library(plotly)

#This doesn't work: the legend is based only on the first geom shape
plot_data <- iris %>% 
  as_tibble() %>%  
  janitor::clean_names() 

plot <- ggplot(data = plot_data, aes(petal_width, petal_length, col = species)) +
  geom_point() +
  geom_line()

plotly::ggplotly(plot)

plot_data <- iris %>% 
  as_tibble() %>%  
  janitor::clean_names() %>% 
  arrange(petal_width)

plot <- ggplot(data = plot_data, aes(petal_width, petal_length, col = species)) +
  geom_point() +
  geom_line()

plotly::ggplotly(plot)

首先使用 plotly::ggplotly 重现提供的 R 示例，比较未排序的 iris 数据与按 petal_width 排列的版本。无论数据行的顺序如何，只要图例都能正确表示点图层和线图层，issue 就完成了。
