----------------------------------------------------------------------
I believe that the test is fine and should not be changed. The {{DroppedColum}}
should filter out every row with a timestamp less or equal to the
{{DroppedColum.timestamp}}. So even if the row and the {{DroppedColum}} have
the same timestamp, it should be ignored.
Now the interesting question is why if you fix the timestamps for the row and
the dropped column, the test is not failing anymore?
