Description

### Apache Hop version?

2.10.0

### Java version?

17.0.2

### Operating system

Linux

### What happened?

(**UPDATE:** probably the issue is related to #4559, I got this in a scenario where the second pipeline doesn't save any valid row in `Copy rows to result`)

Create three pipelines as follows:
1. End the first pipeline with a `Copy rows to result` transform
2. In the second pipeline, start with a `Get rows from result` transform, add some other transforms to manipulate the metadata, and then end with a `Copy rows to result` transform
3. Start the third pipeline with a `Get rows from result` transform

Add those three pipelines in a workflow so that they're executed in the order described above.

The third transform will get the rows from the result of the first pipeline, instead of those of the second one.

No workarounds currently found

Research direction

Reproduce the three-pipeline workflow described in the issue using Copy rows to result and Get rows from result in Hop 2.10.0. Compare the rows received by the third pipeline after the second pipeline manipulates its metadata; done means the third pipeline receives the second pipeline's result rather than the first pipeline's rows.
