INTEGRATED_BUTTONS window_decorations style does *not* disable a window title

[develop7]

What Operating System(s) are you seeing this problem on?

Linux X11

Which Wayland compositor or X11 Window manager(s) are you using?

Mutter 46.5

WezTerm version

wezterm a2f2c07

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

window_decorations = "INTEGRATED_BUTTONS" doesn't disable the window title:

To Reproduce

1. follow https://wezfurlong.org/wezterm/config/lua/config/window_decorations.html regarding INTEGRATED_BUTTONS style (see config below)

Configuration

local wezterm = require 'wezterm'

return {
	default_prog = {"/usr/bin/nu"},
	font = wezterm.font_with_fallback {
		{ family = 'PragmataPro Mono', harfbuzz_features = { 'liga=0'} },
		{ family = 'JetBrains Mono' },
		'Droid Sans Mono',
		"Noto Color Emoji"
	},
	font_size = 14,
	freetype_load_target = 'Light',
	freetype_render_target = 'HorizontalLcd',
	-- use_cap_height_to_scale_fallback_fonts = true,
	color_scheme = 'Tokyo Night Storm',
	default_cursor_style = "BlinkingBlock",
	window_decorations = "INTEGRATED_BUTTONS|RESIZE",
	integrated_title_button_alignment = "Left",
}

Expected Behavior

The window title should disappear, as the doc says

Logs

Debug Overlay
wezterm version: a2f2c07 x86_64-unknown-linux-gnu
Window Environment: X11 GNOME Shell
Lua Version: Lua 5.4
OpenGL: NVIDIA GeForce RTX 3080/PCIe/SSE2 4.6.0 NVIDIA 550.120

Anything else?

In fact, the only style that makes the title actually disappear for me is the NONE, without RESIZE: anything with |RESIZE enables window title back

[develop7]

~~Affects Wayland too~~ UPD: without enable_wayland = false in config the issue does not reproduce on Wayland

please let me know how could I improve this report
