Sending a dataframe from an R actor to a diamond-relation and then into
multiple sinks can cause a typing error to do with the inputs ports of the
sinks on first workflow run. One of the sinks will have its input port type set
properly, but the rest will not, causing the workflow to fail. On subsequent
runs it will work, however.

Additionally, if this R actor is outputting through a port with width 1
(non-multiport), it will behave as if it's a multiport, trying to send data out
4 channels (even though only 1 exists).
