Wrong order of layers from ggplot

[rgaiacs]

The output that I get from ggplot is

and from plotly is

With plotly, the boxplot is behind the violim chart.

The minimal working example that create the above images:

library(tidyverse)
library(plotly)

figure2b <-
  iris |>
  ggplot(aes(x=Species, y=Petal.Length)) +
  geom_violin(aes(fill=Species)) +
  geom_boxplot(width = 0.05) +
  labs(
    title='Iris',
    x="Species",
    y="Petal length",
  )

figure2b_plotly <- ggplotly(figure2b)
