plotly not plotting geom_sf data, "Error in st_coordinates.sfc(sf::st_geometry(model)) : not implemented for objects of class sfc_GEOMETRY"

Hi,

I am trying to convert this geom_sf plot to plotly, but I keep receiving an error:

library(ggplot2)
library(sf)
library(geojsonsf)
library(plotly)

dk_map <- geojson_sf("https://raw.githubusercontent.com/moestrup/covid19/master/test.json")

mainland <- ggplot(data=dk_map) +
  geom_sf()

mainland

ggplotly(mainland)

sessionInfo()

Gives the following output:

> dk_map <- geojson_sf("https://raw.githubusercontent.com/moestrup/covid19/master/test.json")
> mainland <- ggplot(data=dk_map) +
+   geom_sf()
> mainland

> ggplotly(mainland)

I thought this was related to issue #1659, and tried installing the newest version of plotly from github (4.9.2.9000) but am still seeing the error above.

Comienza con el reproducer proporcionado de ggplotly(mainland) y el error st_coordinates.sfc para sf::st_geometry(model). Rastrea cómo llegan los datos de geom_sf al punto de entrada de ggplotly y, a continuación, determina cómo se manejan los objetos sfc_GEOMETRY. Se considera terminado cuando el reproducer se convierte sin el error indicado y produce el mapa interactivo esperado.
