[CSS] Floats impact non-positioned blocks while they must not

Amaya 9.52: on the example attachments "float_1.html" and 
"float_2.html" the floated box impacts the size of the surrounding 
non-positioned blocks while it should impact only their line boxes 
(inline content).

<http://www.w3.org/TR/CSS21/visuren.html#floats>:

> Since a float is not in the flow, non-positioned block boxes created 
> before and after the float box flow vertically as if the float 
> didn't exist. However, line boxes created next to the float are 
> shortened to make room for margin box of the float.

The specification gives illustrations for similar cases I've given 
and I'm attaching sample reference renderings using Mozilla.
