CSS for child selector (*) not minimized correctly

CSS that is valid before minimizing:

```
fieldset.ui-applicationform li * {   
    vertical-align: top;
} 
```

Gets minimized incorrectly and no longer selects the elements as expected:

```
fieldset.ui-gems-applicationform li*{vertical-align:top;}
```

It appears that a required space is missing.
