Cannot update the root element.

[rmorshea]

Current Situation

The 0.33.0 release introduced a regression in which the root element of the layout cannot be updated due to a typo on this line where doc should have been doc.current. We missed this during testing because, under the hood, the display() test fixture uses hotswap under the hood which always modifies one of its children (not the root element). We need an explicit test to check that the root element can be udpated.

Proposed Changes

• quickly fix the issue and make a 0.33.1 release.
• add a regression test to ensure this doesn't happen again in the future.

If I remove json-patch as part of 1.0 I think I can just ignore this altogether.
