The interpretation that it is a % of the layout width is (as you said) the
sensible interpretation and the one that MathPlayer took.  Note that the
layout width might be different when doing linebreaking inside of a table
element -- in that case it would be the column width.

It seems like this is a bug with the spec. I WG will need to figure out the
right way to adjust the spec. Speaking personally, I don't like the idea of
making an exception to the rule about %s and lengths, so I hope there is a
better way to handle this.
