render_label with lat long not working

[cvpalms]

``Describe the bug
After creating a 3d plot using data in a non lat-long based CRS, I cannot get the render_label function to place labels when using lat/long as inputs for the label location, along with the extent of the input dataset. I have tried several variations for the zscale and altitude values just in case the label was appearing way above or below the rendered scene, but no luck there. I was assuming that rander_label function will translate the lat/long values to the native CRS of the input raster or vector GIS layer

library(rgl)

#Step 1: Download the geopackage GIS layer used as input to the test script
#URL: https://data.humdata.org/dataset/kontur-population-switzerland
#Unzip the geopackage file, and place it in the folder named "data" in your R project
# For context, these are hexagons with population counts at 400 meter resolution for all of Switzerland

#Step 2: Read in a GIS layer of polygons with population counts
#Note that this geopackage layer is in coordinate system 3857 (WGS 84 Pseudo-Mercator where the units are meters instead of lat/long degrees)
in_sf = read_sf("data/kontur_population_CH_20220630.gpkg")

#Step 3: Convert the GIS layer to a raster, with a cell size of 400 meters
r = raster(in_sf, res = 400)
rast <- fasterize(in_sf, r, field = "population", fun="max")

#Step 4: Convert the raster to a matrix for 3d plot
elmat = raster_to_matrix(rast)

#Step 5: Setup colorramp for raster rendering by population
colors = met.brewer("OKeeffe2")
texture = grDevices::colorRampPalette(colors)(256)
swatchplot(texture)

#Step 6: Render the 3d scene
#Step 6a: Close RGL window if it's already open
if (length(rgl.dev.list()) > 0) {
rgl.close()
}
#Step 6b: Create 3d Plot
elmat |>
height_shade(texture) |>
plot_3d(heightmap = elmat
,zscale = 400 #Each cell in the raster is 400 meters on each side
)

#Below is the step where the issue occurs. The label will not render. It should appear floating over the dark red patch on the far left side of the scene
#Question: Does the render_label function support scenarios where lat/long values are provided for the label location,
#but the extent input has a CRS that is meter based instead of lat/long based?

#Step 7: Render a label for Geneva using lat long. Raster used for extent input uses CRS 3857 (meters)

lat = 46.204391,
