I found that we have to change the current algorithm to reproject <shadow>.

Currently, we resolve <content> from the youngest shadow root. However, when we reproject <shadow>, we have to resolve <content> and <shadow> from the oldest shadow root, since we have to know what elements are distributed to <shadow>.

This is an example.
host ------- SR -------------- SR (younger)
 |- div (A)   |-div (C)         |-div -------- SR
 |- div (B)   |-content[B]         |-shadow     |-content[div]#target
              |-shadow

When we resolve  content[div]#target, we have to resolve all the other shadow and content.
This might be a drastic spec change.
