LibWeb: Fix width calculation for floating replaced elements

Browse source 
The path for floating, replaced elements must not fall through to the
path taken for floating, non-replaced elements. The former works like
inline replaced elements, while the latter uses a completely different
algorithm which doesn't account for intrinsic ratio. Falling through
overrides the correct value computed by the former.

Fixes #19061.
