Andreas Kling 8c6786d70b LibWeb: Ignore non-overlapping floats in intrinsic widths ...

BlockFormattingContext::greatest_child_width() tried to decide whether
a line overlapped a float by comparing a line-relative baseline
against float edges stored in containing-block coordinates. That also
used `||`, so later lines could keep inheriting float width even after
the float had ended.

Measure overlap using each line box's top and bottom edges in the same
coordinate space as the float margins instead. This fixes
shrink-to-fit and max-content sizing for inline children after short
floats.

Add left and right tests where a later forced-break line is longer
than the line next to the float.
