> +	Walk up DOM/hosted tree rather than render tree.

We can't land files with tabs in them.

> WebCore/page/EventHandler.cpp:1869
>                      && m_frame->selection()->toNormalizedRange()->compareNode(n, ec) == Range::NODE_INSIDE

Can this run JavaScript?

> WebCore/page/EventHandler.cpp:1875
> +            node = node->parentOrHostNode();

Are we holding references during this walk?
