User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6

Using percent values for padding gives wrong values for the scroll height computation and has no further effect.

Please have a look at the attached reproduce. 

Reproducible: Always

Steps to Reproduce:
1. Set padding right on a textarea to 10%, padding top and bottom to 1px
2. Calculate the scroll height of the element
Actual Results:  
1. The scroll height = height + padding + padding.
2. The padding-right:10% has no effect.

Expected Results:  
1. Expected scroll height = height + padding.
2. The padding-right:10% should have about the same effect as padding-right:50px, in this case.
