Route passes a oneway road in the wrong direction error involving trolleybuses

[Gafigglethorp]

I was editing a trolleybus route and got the error about passing a oneway road in the wrong direction.

When tagged as oneway:trolleybus=no, the error persists.
When tagged as oneway:bus=no, the error goes away.
However, this is a trolleybus route, and the exception is exclusively for trolleybuses, not regular buses.
