Description donjjordan 2014-12-11 05:05:01 UTC 
Regarding the algorithm for cloning the contents of a Range at https://dom.spec.whatwg.org/#concept-range-clone

Step 15 reads:

<snip>

15. For each contained child in contained children:

    1. Let clone be a clone of contained child.

    2. Append clone to fragment.

</snip>

Step 15 should read:

15. For each contained child in contained children:

    1. Let clone be a DEEP clone of contained child.

    2. Append clone to fragment.


All of the other cloning operations in the Range specification use a shallow clone (e.g. node.cloneNode(false)). The above case only requires a deep, recursive clone of the contained child (e.g. node.cloneNode(true)). An experienced implementer can figure it out, but I think it should be clarified in the specification.
