[css21] Computed value of percentage table row heights

The following proposal addresses Issue 61 [1].

Per CSS2.1, 17.5.3 [2] : 

>> Percentage heights on table cells, table rows, and table row groups compute to 'auto'.

A number of testcases [3][4][5], however, indicate that current implementations attempt to honor the specified percentage heights for these elements. In several cases, however, their behavior differs as detailed by Saloni last year [6]. 

I propose replacing the statement above with :

>> CSS 2.1 does not define how the height of table cells, table rows and table row groups is calculated when their height is specified using percentage values.
