Prooph Event Stream Projection from merged streams event ordering

How should the behaviour be in a single stream? It looks like it projection runs using the no order instead of created_at. So I guess we have to rewrite our wrongly ordered manually migrated stream.

We rewrote the event stream ordered by "created_at" and re-setting the no. The projection now looks as expected.

If I see this correctly then writing a projection fromStreams does not work if one of the streams has inconsistent ordering between no and created_at. Though this should not happen when correctly using the lib. But the mentioned sort does not seem to solve it.
