Here's what works but it feels like a hack:
RenderBlock* none = new (renderArena()) RenderBlock(document());
RefPtr<RenderStyle> newStyle = RenderStyle::create();
newStyle->inheritFrom(style());
newStyle->setDisplay(INLINE_BLOCK);
newStyle->setMaxWidth(Length(0,Fixed));
newStyle->setMaxHeight(Length(0,Fixed));
newStyle->setOverflowX(OHIDDEN);
newStyle->setOverflowY(OHIDDEN);
none->setStyle(newStyle.release());
RenderBlock::addChild(none, beforeChild);
none->addChild(child);
I basically create an inline block with zero width and height and then
set the overflow to hidden.
