lineage_view_issue shows the image you start seeing as you scroll the lineage  area to the
right.

> I have a slightly complex lineage which is like this:
> [DataSet 1] -> (3 processes) -> [DataSet 2] -> (1 process) -> [DataSet 3]
> When I click on DataSet1, the lineage graph is showing correctly.
> When I click on DataSet2, the lineage graph is broken. What is happening is that there
are 2 dangling processes on the input side of DataSet 2 which are not linked to the DataSet
1. Only one of the processes seems linked. It appears that maybe the graph walking is not
taking into effect multiple inputs to a vertex like DataSet 2.
> The API response is right. I will upload images of working and failing lineages with
the corresponding responses in follow-up comments.
