Steps to reproduce:

1. Open a process with many subprocesses
2. In the subprocess pane, use the arrow to page forward a few times
3. Refresh the page in your browser (e.g., because you want to see if any of the displayed subprocesses have finished)

Expected result: The subprocesses pane reloads on the same page you were before, with the same list of processes displayed but with updated status and other information.

Actual result: For me right now on 2.5.0, the pane shows the message "No subprocesses available for listing. The current process may not have any or none matches current filtering."

A user on a 2.6.0 rc reports that the pane loads fine, but returns to the first page of subprocesses, losing their place.
