No, it should have had a computed height of 50% of the computed height 
of that box.  The computed height of the anonymous box is auto, and 
percentages of auto compute to auto.

There are multiple boxes generated here, so "the box" is nonsensical.

I believe in CSS each box is generated by a specific element.  But I 
could be wrong; Bert's pointed out cases where I was wrong about box 
generation before.  I wish it were defined somewhere outside Bert's 
brain.  ;)

Not really, no.
