ENYO-690: Handle non-LESS styles with multiple measurement values.

### Issue
Only LESS variables with multiple measurements were being properly parsed, resulting in only the first measurement of a CSS rule involving multiple measurements being used.

### Fix
We now fully parse directly-set CSS rules that involve multiple measurements.
