Reviewed by Antti Koivisto.

Inline boxes should contribute with their font based metrics to line box height (when they have content).

* LayoutTests/platform/mac/fast/block/lineboxcontain/font-replaced-expected.txt: Content is not supposed to be scrollable.
* Source/WebCore/layout/formattingContexts/inline/InlineFormattingGeometry.cpp:
(WebCore::Layout::InlineFormattingGeometry::inlineLevelBoxAffectsLineBox const): Move lineBoxContain functionality over to InlineLevelBox.
