> In {{SecondaryIndexManager.onUpdated()}}, we fail to copy the {{DeletionInfo}} from the
existing and new rows before notifying the index of the update.  This leads the index to believe
a new, live row has been inserted instead of a single-row deletion.  It looks like this has
been a problem since 3.0.0-beta1.
> I've attached a simple patch that fixes the issue.  I'm working on a full patch with
tests, etc.
