Multiple Edge classes in shortest path doesn't work

[Suhas]

In ODB version 3.0.15, the "shortestPath" function has a parameter "edgeClassName" which is documented as follows:

• edgeClassName, optional, is the edge class to traverse. By default all edges are crossed. Since 2.0.9 and 2.1-rc2. This can also be a list of edge class names (eg. ["edgeType1", "edgeType2"])

The following works.

shortestpath($from, $to, "OUT", "EdgeClassA")

None of the following work. Returns zero records.

shortestpath($from, $to, "OUT", ["EdgeClassA"])
shortestpath($from, $to, "OUT", ["EdgeClassA", "EdgeClassB"])

But on this page, it mentions it has been fixed in v2.x. Can someone verify this issue in v3.x? Does another ticket need to be opened on Github?
