Some geoms always appear below others

Rendering of violin plots with box plots (to provide median & stddev) is in wrong order when using ggplotly.

library(ggplot2)
library(plotly)

p <- ggplot(iris,aes(Species,Sepal.Length))+
  geom_violin()+geom_boxplot(width=.1)
q <- ggplotly(p) 

the ggplot (p) will render as expected with violin plots:

the ggplotly (q) will render with the box plot behind the violin plot (and larger than expected):

先使用提供的 R 示例和 ggplot2、ggplotly，然后跟踪小提琴图和箱线图的转换与渲染过程。通过比较 ggplot 和 ggplotly 的输出确认该问题；当箱线图以预期的大小显示在小提琴图前面时，即表示完成。
