+			The used value of 'height' is determined as for inline replaced elements.
+			If 'margin-top' or 'margin-bottom' is specified as 'auto' 
+			its used value is determined by the rules below.
+			(...)
+			If 'height' and 'width' both have computed values 
+			of 'auto' and the element also has an intrinsic height, 
+			then that intrinsic height is the used value of 'height'. 
+			(...)
+			If 'bottom' is 'auto', replace any 'auto' on 'margin-top' 
+			or 'margin-bottom' with '0'. 
+			If at this point there is only one 'auto' left, 
+			solve the equation for that value.

+			In this test, bottom will be -96px because the height of the
