I’m trying to create an interactive plot with ggiraph using my organization’s ggplot theme. The fonts specified there are as follows:

font_light <- "Segoe UI Semilight"

The theme uses the fonts this way:

# font_import() # did this once
loadfonts(device = "win") # do this every session

theme_org <- function() {
   theme(
      # Text Elements
      plot.subtitle = element_text(
        family = font_light,
        size = 11,
        hjust = 0,
        margin = margin(b = 10)
      )
   )

When I use this theme to produce a regular ggplot there is no issue. But when I use that ggplot object in a girafe() call I get the following error:

Error in `girafe()`:
! Font family 'Segoe UI Semilight' has not been found on your system or is not registered.
ℹ You can use a google font with `gdtools::register_gfont()`.
ℹ You can use any font with `systemfonts::register_font()`.

Here’s what my Segoe system fonts look like:

> systemfonts::system_fonts() %>% filter(grepl("Segoe", family))

Any advice would be greatly appreciated!

I’ve read the discussion here but it doesn’t seem to apply to my situation. I’ve tried registering the font but it seems like ggplot and ggiraph are reading the family name differently.
