Getting a few errors with Sway and Icecat

[Oleander]

Hello,
is anyone getting any of these errors with Sway and Icecat? They show
up when shutting down my laptop with `loginctl poweroff`:

```
[warning] Waybar has been built without rfkill support

The XKEYBOARD keymap compiler (xkbcomp) reports:
> Warning: Unsupported maximum keycode 708, clipping.
> X11 cannot support keycodes above 255.
Errors from xkbcomp are not fatal to the X server

My .bash_profile

```
# Honor per-interactive-shell startup file
if [ -f ~/.bashrc ]; then . ~/.bashrc; fi

# Set environment variable for scripts
export PATH="$PATH:/home/oleander/bin/"

# Start Sway automatically on tty1 and enable Wayland for Firefox/Icecat
if [ -z $DISPLAY ] && [ "$(tty)" = "/dev/tty1" ]; then
#export MOZ_ENABLE_WAYLAND=1
exec dbus-launch sway
fi
```
Another weird bug I'm experiencing is Icecat not recognizing my cursor
theme when running under Wayland with MOZ_ENABLE_WAYLAND=1 configured in
my `.bash_profile`. This was also reported by some Nix users here:
https://github.com/NixOS/nixpkgs/issues/207339
