window-title-font-family doesn't affect tab titles?

[ncfavier]

I'm using Ghostty 1.1.0 on Linux. Setting window-title-font-family in my configuration doesn't seem to make a difference as to which font is used for tab titles: they are always rendered in the default sans-serif. I've tried many different fonts. Am I missing something? The docs for that option say

The font that will be used for the application's window and tab titles.

same situations here

refer to the doc:
https://ghostty.org/docs/config/reference#window-title-font-family

my config:

    window-title-font-family = "Iosevka";

Depending on how you look at it this could either be a documentation bug, or a bug in Ghostty as the GTK apprt definitely does not change the tab title font when this is set. Not sure about macOS but probably a similar thing.

@jcollie I think Ghostty bug looking in GTK apprt it is supposed to set some css for this

ghostty/src/apprt/gtk/App.zig

Lines 1066 to 1072 in 38908e0

	if (config.@"window-title-font-family") |font_family| {
	try writer.print(
	\\.window headerbar {{
	\\ font-family: "{[font_family]s}";
	\\}}
	, .{ .font_family = font_family });
	}

Yeah, that's exactly what I was referring to. The question is do we fix the docs (remove reference to changing tab title font) or do we fix the implementation (add CSS to change the tab title font). Since this is a cross-platform config I think we need some feedback from a macOS-savvy dev to let us know if it's possible to change the tab title font on macOS (without a custom tab implementation).

Also, do we want the tab title font to follow the window title, or should we have a separate tab-title-font-family config to change the tab title font?
