[css-align] computed value of 'align-self: auto'

Reading the specification literally (although it's kinda clear
what's intended), 
https://drafts.csswg.org/css-align/#propdef-align-self says:

  # The auto and stretch keywords are as defined in §5.1
  # Inline/Main-Axis Alignment: the justify-self property.

which in turn says:

  # The auto keyword computes to itself on absolutely-positioned
  # elements, and to the computed value of justify-items on the
  # parent (minus any legacy keywords) on all other boxes, or start
  # if the box has no parent. Its behavior depends on the layout
  # model, as described below.

which means that the computed value of 'align-self: auto' is derived
from the value of 'justify-items' on the parent element.  I believe
deriving from 'align-items' was intended.
