[Bug 17023] [Shadow]: Can an InsertionPoint be a shadow host?

It seems you guys gave me comment when I was writing the followings: :)

My suggestions are:

- For active InsertionPoints, attached ShadowRoots should not be used.
- For inactive InsertionPoint, attached ShadowRoots should take effect.
- It is okay to attach a ShadowRoot to either active or inactive
InsertionPoints.
- It is okay to move a InsertionPoint inside the ShadowRoot or outside the
ShadowRoot. That might change its active/inactive status, but that should not
get rid of its attached ShadowRoots.
