Raster doesn't display in mapview/leaflet when using in Shiny together with cubeViewOutput

Hi, and thanks for an awesome package. I've been playing with Shiny, leaflet and cubeView and hit an issue that I don't know whether it is mine own, a computer's one, or made by some possible interference in mapview package. When cubeViewOutput is deployed in one of the panels, the raster layer in leaflet (or mapview) panel is not displayed (no error or warning). It is not an issue with points that are working as expected. Everything works fine also when the cubeViewOutput is removed from the panel.

Minimal reproducible example:

ui.R

library(shiny)
library(leaflet)
library(mapview)

shinyUI(navbarPage("App", 
                   tabPanel("Map",
                            div(class="outer",
                                tags$style(type = "text/css", ".outer {position: fixed; top: 50px; left: 0; right: 0; bottom: 0; overflow: hidden; padding: 0}"),
                                leafletOutput("map", width = "100%", height = "100%")
                            )
                   ),
                   tabPanel("3D explorer",
                            cubeViewOutput("cubemap", width = "auto", height = "auto")
                   )
)
)

server.R

library(shiny)
library(leaflet)
library(raster)
library(mapview)

gp.stack <- stack(system.file("extdata", "kiliNDVI.tif", package = "mapview"))

shinyServer(function(input, output, session) {

  output$map <- renderLeaflet({
    leaflet() %>% addTiles() %>%
      addRasterImage(gp.stack[[1]], opacity = 0.5, project = TRUE, layerId="rasimg")
  })

  output$cubemap <- renderCubeView({
    cubeView(gp.stack)})
})
