This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Spec says: "The nodes with a unique id and named elements are not addressable from any attributes of elements in shadow host's document" I think that the reverse must also be true: "The nodes with a unique id and named elements in shadow host are not addressable from any attributes of elements in shadow tree document" ?
This is ultimately part of bug 20139, since all those statements are just informative, and are merely an effect of the shadow tree being a separate tree from a document. *** This bug has been marked as a duplicate of bug 20139 ***
