Workspaces loading page attempts to create new job after job is stopped

I just found a workspaces bug in the portal UI.
Process to recreate:
Create a workspace, start a job, keep that new tab/window open, click stop job on the workspaces list from a separate tab.
Issue:
The page that gets opened when a job is launched attempts to create a new job even if the job is stopped from the workspaces list. You can see that happen in this screenshot, the “start” PUT request gets sent each time the jobs page detects that there is no running job for that workspace (I think) in the jobs GET request.
