Gallery.js:17105 Uncaught TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'.

if (child) {
        var patches = (0, _diff2.default)(child[PREVIOUS_WIDGET_KEY], root);
        (0, _patch2.default)(child, patches);
      } else {
        child = (0, _createElement2.default)(root);
        node.appendChild(child);
        (0, _delegator2.default)(node);
        (0, _initializeWidgets2.default)(child);
      }

This is inside the render method. Why are you attempting to append the child when it's false-y?

hmmm not sure where that's coming from. no source map? i don't think i wrote that code.

Going to close because I've just merge the full rewrite branch.
