Bug in Combine Columns by Header node?

I'm using KNIME 2.10.4. In the Combine Columns by Header node the value defined for "Name of appended column" does not get applied in the appended output column. The output column header is a concatenation of the combined headers. Is this a bug?

Consider the description.

Also, the Column Aggregator has a superset of the capabilities, apart from quoting.

Yes - but I would expect that if the option to define the output column name is a part of the node, it should work. It doesn't.
