Ghostty does not seem to be setting the bold-italic family when using Iosevka Extrabold Italic

[msaifi03]

Here's my config:

font-family = "Iosevka Medium"
font-family = "Font Awesome 6 Free Solid"
font-family-bold = "Iosevka Extrabold"
font-family-bold-italic = "Iosevka Extrabold Italic"
font-family-italic = "Iosevka Medium Italic"

And yet:

info(font_shared_grid_set): font regular: Iosevka Medium
info(font_shared_grid_set): font regular: Font Awesome 6 Free Solid
info(font_shared_grid_set): font bold: Iosevka Extrabold
info(font_shared_grid_set): font italic: Iosevka Medium Italic
info(font_shared_grid_set): font bold_italic: Iosevka Medium Italic

Here is the relevant output from ghostty +list-fonts:

From the Discord discussion, N.B.:

info(font_shared_grid_set): font italic: Iosevka Medium Italic
info(font_shared_grid_set): font bold_italic: Iosevka Medium Italic

This font that it falls back to is the OP's system default monospace font.
