Remove obsolete/unactionable warnings

On Windows 10 (version 21H2, build 19044.3448) using RStudio 2023.06.1, when I run the following code

library(ggplot2)
library(plotly)

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

I get the following warnings:

Warning messages:
1: 'scattergl' objects don't have these attributes: 'hoveron'
Valid attributes include:
'connectgaps', 'customdata', 'customdatasrc', 'dx', 'dy', 'error_x', 'error_y', 'fill', 'fillcolor', 'hoverinfo', 'hoverinfosrc', 'hoverlabel', 'hovertemplate', 'hovertemplatesrc', 'hovertext', 'hovertextsrc', 'ids', 'idssrc', 'legendgroup', 'legendgrouptitle', 'legendrank', 'line', 'marker', 'meta', 'metasrc', 'mode', 'name', 'opacity', 'selected', 'selectedpoints', 'showlegend', 'stream', 'text', 'textfont', 'textposition', 'textpositionsrc', 'textsrc', 'texttemplate', 'texttemplatesrc', 'transforms', 'type', 'uid', 'uirevision', 'unselected', 'visible', 'x', 'x0', 'xaxis', 'xcalendar', 'xhoverformat', 'xperiod', 'xperiod0', 'xperiodalignment', 'xsrc', 'y', 'y0', 'yaxis', 'ycalendar', 'yhoverformat', 'yperiod', 'yperiod0', 'yperiodalignment', 'ysrc', 'key', 'set', 'frame', 'transforms', '_isNestedKey', '_isSimpleKey', '_isGraticule', '_bbox'
 
2: 'scattergl' trace types don't currently render in RStudio on Windows. Open in another web browser (IE, Chrome, Firefox, etc).

• The second warning is outdated. The plot renders fine on the viewer panel and I successfully can zoom and interact with it. I suggest removing it.

• The first warning was reported back in 2019 on #1582. It is useless to me (and I guess most users) since it is not clear what can we do to avoid it. It is also weird because it happens on a simple plotly use-case. I am using this function, but it would be nice if it could be addressed:

library(ggplot2)
library(plotly)

workaround_hoveron_warning <- function(p) {
  p$x$data <- lapply(p$x$data, function(item) {
    item$hoveron <- NULL
    item
  })
  p
}

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

Questions

• Would a PR removing the RStudio on Windows warning be acceptable?
• Is there a better approach for avoiding the hoveron warning?

Thanks!

Start from the toWebGL() path and the code that emits the scattergl hoveron and Windows/RStudio warnings; no source files or tests are named in the issue. Reproduce the supplied ggplot2/plotly example on the stated setup, then verify the obsolete warning is gone and the remaining warning behavior is addressed.
