In DOM traversal, `display:contents `elements don't generate boxes, but their styles still need to apply to children. `ModernContainerBuilder` now keeps track of `display:contents` ancestors during traversal then apply their style to text runs. In `InlineFormattingContextBuilder::push_text` only use same style parent if both selected and current inline style are identical.
