WezTerm version

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

I have configured wezterm to use "Source Code Pro" which seems to be found and accepted but the glyphs are actually rendered using the built-in "JetBrains Mono" font.

To Reproduce

❯ wezterm ls-fonts
Primary font:
wezterm.font_with_fallback({
  -- /home/tobbe/.local/share/fonts/Source Code Pro-Regular.otf, FontConfig
  -- Assumed to have Emoji Presentation

  -- <built-in>, BuiltIn
  "JetBrains Mono",

  -- /usr/share/fonts/truetype/noto/NotoColorEmoji.ttf, FontConfig
  -- Assumed to have Emoji Presentation
  -- Pixel sizes: [128]
  "Noto Color Emoji",

  -- <built-in>, BuiltIn
  "Symbols Nerd Font Mono",

})

Anything else?

I have checked if for some reasons the font files are broken but as far as I can tell, they seem to be ok and to contain the glyphs which are not used.

I have switched to another font which does work as configured. So maybe this bug is not resolved, but I will not put any effort into resolving this anymore.
