Extending alacritty terminal over two monitors

### System

OS: Ubuntu 20.04
Version: alacritty 0.11.0 (8dbaa0bb)
Linux/BSD: gnome shell

I have been able to span alacritty terminal (v 0.10.1) over two monitors using the config file :
window:
```
# Window dimensions (changes require restart)
dimensions:
columns: 274
lines: 126

# Window position (changes require restart)
position:
x: 0
y: 0

# Window decorations
decorations: none
```
This is not possible anymore with the newest release. Can this be fixed?
