Suppose the following tree:

<div id='host' contenteditable>
  -- <shadow-root>
          <div id='node-in-shadow-root'>
              <content />
          </div>
  <div id='child-of-host'>hello</div>
</div>

"8.4 Editing" says 'The value of the contenteditable attribute must not propagate from shadow host to its shadow DOM subtrees.'

My question is 'Does the contenteditable attribute propagate from shadow host to its child node which is distributed into an insertion point?'.

My understanding is it should propagate. So the result should be:

#host: contenteditable
#node-in-shadowroot:  Is not contenteditable
#child-of-host: contentediable

Is my interpretation correct?
