Extra space from config snippets

Am I doing something wrong?

In my config I have
```
"config": {
	"css": {
		"snippets": {
			"trr": "transform: rotate(${1:45}deg);",
		}
	}
}
```

but when this abbreviation expand in the CSS, it looks like this

```
transform: rotate(45 deg);
```

the space after 45 is incorrect - it's shouldn't be there
