[LayoutNG] Correct overflow inside anonymous blocks inside %-insets.
NGPhysicalLineBoxFragment::ScrollableOverflow() compared the computed
style passed as container_style to the computed style of each child,
and it would calculate the child's relative offset only if they
differed. All element nodes have their own computed style, so this only
mattered for text nodes. However, if the container was an anonymous
block, they'd always differ, since the computed style of a text node
is the same as that of the parent DOM node. This is an implementation
detail; we save some memory by letting text nodes share computed style
objects with their containing DOM node. But that also means that extra
care is required when working with ComputedStyle objects associated
with text nodes: basically, treat all non-inherited-by-default
properties (such as 'position', 'top' and 'left') as if they were set
to their initial value.
