Fix rstudio windows warning

[zeehio]

The RStudio on Windows with scattergl is working for me as documented in #2296.

I'd say this closes #1214.

I would appreciate if someone (@daattali ?) who had issues with webgl rstudio and windows could verify the issues are also solved for them by running this on RStudio and seeing the plot in the viewer panel:

library(ggplot2)
library(plotly)

gplt <- ggplot(iris) + geom_point(aes(x= Sepal.Length, y = Sepal.Width))
gplt |> toWebGL()

Thanks!
