How does the pointsize argument work in ggiraph::girafe?

Reading the help, it looks like this is the way to set the font size in the html output. However it doesn't seem to do anything in my code??

library(tidyverse)
library(ggblanket)
library(ggiraph)
library(palmerpenguins)

p <- penguins |>
  mutate(id = row_number()) |> 
  ggplot() +
  geom_point_interactive(
    aes(
      x = flipper_length_mm,
      y = body_mass_g,
      tooltip = glue::glue("{species}
                           {flipper_length_mm} mm
                           {body_mass_g} g"
      ),
      data_id = id
    ),
    size = 1)

# girafe(ggobj = p, 
#        width_svg = 6, 
#        height_svg = 3.5, 
# )

# girafe(ggobj = p, 
#        width_svg = 6, 
#        height_svg = 3.5, 
#        pointsize = 5
# )
