Title: Fix layout of Create Account / Login when rendering Wikipedia.

When calculating the preferred width for a block, accumulate
the left and right float widths of children separately, which
is then max'ed with the normal flow widths later on.

Ref bug #2554 - improves the layout of the top bar.
