Can't set fill and colour on geom_sf when thematic is on

[PaulC91]

Hi, I noticed manually set fill and colour properties on a geom_sf are ignored when thematic is turned on.

Is there any way to override this behaviour?

Thanks.

library(sf)

library(ggplot2)
library(thematic)

nc <- st_read(system.file("shape/nc.shp", package="sf"), quiet = TRUE)

# without thematic
ggplot(nc) + geom_sf(fill = "red", colour = "white")

# with thematic
thematic_on(bg = "grey20", fg = "white", accent = "blue")  
ggplot(nc) + geom_sf(fill = "red", colour = "white")
