addRasterImage doesn't work if latitude limits are -90 and +90

[edwardlavender]

I tried to use addRasterImage to add a raster with limits -180, 180, -90, 90 to a leaflet map.

I expected the raster to be added to the map as usual, but it wasn't. The issue seems to come from the latitude limits. If you reduce the limits slightly, the map is produced as expected.

Here is a reproducible example:

library(raster)
library(leaflet)

packageVersion("raster")  # 3.6.11
packageVersion("leaflet") # 2.1.1

# This works
r <- raster(nrows = 180, ncols = 720,
            xmn = -180, xmx = 180, ymn = -89.999, ymx = 89.999)
r[] <- runif(prod(dim(r)), 0, 20)
leaflet() |>
  addTiles() |>
  addRasterImage(x = r)

# This doesn't work
r2 <- raster(nrows = 180, ncols = 720,
            xmn = -180, xmx = 180, ymn = -90, ymx = 90)
r2[] <- runif(prod(dim(r2)), 0, 20)
leaflet() |>
  addTiles() |>
  addRasterImage(x = r2)

This is occurring for me too. I have reduced the latitude limits but it would be great if there was a fix.
