Added the previous process group to the end of the URL so that it may be centered with the click of the zoom button when navigating up a process group via the LeaveProcessGroup function.

Thanks for the PR @homer-rich! I'll have a look.

I haven't had a chance to fully review, but I wanted to clarify the desired behavior. The current behavior of leave process group will navigate up one level and restore the users previous viewport. Here we are trying to retain that functionality but also select the child Process Group was just exited.

I have some concern at first glance (but I need to verify) that we're losing the centering behavior which would trigger when a user navigates to a selected component without having established a viewport to restore (like through a deep link).

That is the correct interpretation of what I am trying to accomplish with the desired behavior. I was wondering if there was a way to respond differently if the link was deep vice using the Leave Group function. I'm new to JS/TS development, apologies in advance.
