"Depends" Funnel Edge Case

Seeing an edge case in which a funnel step is not working properly.

Here is a graphic in which there are two parameterized runs (Run1, Run2). If one of the postprocessing steps for Run1 fails (failure visualized as a red square), I expect the subsequent and dependent post-processing steps to fail. Maestro is doing this successfully.

The issue is that the Plotr step for other, separate runs is also failing. Plotr depends on Postr_, however I just want it to depend on the postr_ steps for its parent run, NOT all other runs.
