I think this is one for Finn :-) at least I am not sure how to fix it.
The line-height property has a special inheritance rule. If it is a
number (and the enum "normal" is considered a number) inherit the
specified value otherwise inherit the calculated value. In the current
system if the specified value is a percentage it still inherits the
percentage that is the specified value not the calculated value.
I have committed a fix. The specified value is only stored for numbers.
Now we just need to decide what a number is <wink>.
