boxplots are always placed below other geometries regardless of order

[stragu]

Hi there

I noticed that with ggplotly() taking a ggplot object, the layering of geometries is not respected by boxplots, which always end up underneath everything else (in my testing at least).

See this reprex:

library(ggplot2)
bp <- ggplot(mpg, aes(x = class, y = hwy)) +
  geom_jitter(colour = "orange") +
  geom_boxplot()
# jitter is below boxplots
bp

# ggplotly puts boxplot underneath everything else
library(plotly)
#> 
#> Attaching package: 'plotly'
#> The following object is masked from 'package:ggplot2':
#> 
#>     last_plot
#> The following object is masked from 'package:stats':
#> 
#>     filter
#> The following object is masked from 'package:graphics':
#> 
#>     layout
ggplotly(bp)
#> TypeError: Attempting to change the setter of an unconfigurable property.
#> TypeError: Attempting to change the setter of an unconfigurable property.

Interestingly, the TypeError doesn't show up in my console, but it does in the reprex output.

Using R 4.0.2 on Ubuntu 18.04 with RStudio 1.3.1073, ggplot2 3.3.2 and plotly 4.9.2.1

This remains a problem, #2172 is a duplicate. I feel like this may be a base plotly issue, as the trace order seems to be respected just fine after the ggplotly conversion.

Seems like there is functionality to control this upstream in plotly.js (see plotly/plotly.js#6918), not sure which version it made it into. I suppose #866 was the original report of this.
