Description Shinya Kawanaka 2012-02-01 22:04:42 PST
Let's consider adding a new shadow subtree to element having a built-in shadow subtree.
Such element may have a code like:
  ensureShadowRoot()->firstChild() ...

If ensureShadowRoot() returns the youngest shadow root, this code may crash.
We should guarantee that elements can take built-in shadow root.
