height' and 'bottom' are 'auto' and 'top' is not 'auto',
then the height is based on the content per 10.6.7,
set 'auto' values for 'margin-top' and 'margin-bottom' to 0,
and solve for 'bottom'

In this test,
top used value will be 25px
height used value will be 100px
vertical margins will be 0px
bottom used value will be -125px
because the computed height of containing block is 0px.
