insert without origin fails

[JoernT]

using todo2.html as foundation:

When replacing existing insert with: <fx-insert ref="task" at="1" position="before"></fx-insert>

The data still get inserted but the repeat is not showing the new entry.

When adding in a origin it works and renders the new item.

<fx-insert ref="task" origin="task" at="1" position="before"></fx-insert>
