[css-pseudo] Don't propagate style to children of normal markers

In r720875 I changed the pseudo type of the style used for markers with
'content: normal' from kPseudoIdNone to kPseudoIdMarker. This had the
side effect that they started to propagate style to its children,
producing a 90.6%-99.9% performance regression in the
flexbox_with_list_item test.

This patch prevents that style propagationg for normal markers, fixing
the perf regression. Markers with 'content' different than 'normal' are
still propagated since it's necessary in that case.
