REGRESSION: Parallel nodes are not selectable in running pipeline

Problem
When running a pipeline with parallels the parallels are not selectable

Steps to reproduce

1. Create a pipeline using https://github.com/i386/app-store-demo
2. Run master
3. Try to click on any of the parallels
4. You won't be able to select any parallels

Expected behaviour
Parallels are selectable just like stages.

Note

• Expected regression from merging in karaoke_reloaded
• Needs to be fixed before 1.1 release, which is why this is marked BLOCKER
