Noticed this one the other day, if you have a pipeline job with build parts in the queue and you're looking at a view with the filter build queue option, then the build part doesn't show up in the build queue.
Notice how the build queue is empty in the second image while there clearly is a build part queued for the job test in the main view.
The problem is that, in hudson.model.View#filterQueue(List<Queue.Item> base), it only checks if the queue task is in the list of filtered jobs, however that is not true for pipeline parts as the task is a step and not the job it self. To solve this, simply also check if Queue.Task#getOwnerTask() is in the list of filtered jobs (do this recursively).
I will make a pull request for this, only problem is how to write a test for this, doesn't seem like there are any existing similar tests for views
Suggestions and alternative solutions are welcome
