addGlPoints with L.CRS.Simple not rendering points

[LucianneY]

Hello, thanks for this package.

I'm experiencing issues using addGlPoints with L.CRS.Simple. My problem appears to be very similar to the one described in issue #13 , so before diving into my codes I would like to first replicate the working example, but the working example provided there does not render anything for me.

Below is the example code from issue #13

library(leafgl)
library(mapview)
library(leafem)
library(sf)

# Transform spatial data to CRS 3035
brew <- st_transform(breweries, 3035)
fran <- st_transform(st_cast(franconia, "POLYGON"), 3035)
trls <- st_transform(st_cast(trails, "LINESTRING"), 3035)

m <- leaflet(
  options = leafletOptions(
    minZoom = -1000,
    crs = leafletCRS(crsClass = "L.CRS.Simple")
  )
)

m %>%
  addGlPoints(brew, popup = "founded") %>%
  addGlPolygons(fran) %>%
  addGlPolylines(trls) %>%
  setView(lng = 4389376, lat = 2964480, zoom = -9) %>%
  addMouseCoordinates()

I originally used the CRAN version and also tested the GitHub version, but neither was able to replicate the example.
