Describe the bug / provide steps to reproduce it

ui_font_features doesn't seem to change the font at all.

I have set the editor to use the Inter font installed into my system, but enabling features doesn't work at all.

	"ui_font_size": 14, // Works
	"ui_font_family": "Inter", // Works
	"ui_font_features": {
		"cv08": true // Doesn't work, it's supposed to make I serif
	},

By checking the font files on FontForge I can confirm it does have the feature available.

I have no idea of how to use non-system fonts to test.

Environment

I don't think this is related to the font.

On Linux modifying the font features doesn't work currently, IIRC.

Any ETA on when this may be fixed? I'm really liking Zed so far but this is a big blow to me, as I'm a Linux user, and am not a fan of ligatures.

Use this to disable ligatures for now.
Just turn off calt and dlig.
