LibWeb: Skip out-of-flow boxes when wrapping inlines in anonymous block

Browse source 
Out-of-flow boxes (floating and absolutely-positioned elements) were
previously collected and put in the anonymous block wrapper as well, but
this actually made hit testing not able to find them, since they were
breaking expectations about tree structure that hit testing relies on.

After this change, we simply let out-of-flow boxes stay in their
original parent, preserving the author's intended box tree structure.
