1. Deploy Eclipse Che
2. Update CheCluster CR to use quay.io/eclipse/che-dashboard:pr-878 as the dashboard image:

   spec:
     components:
       dashboard:
         deployment:
           containers:
             - image: quay.io/eclipse/che-dashboard:pr-878

3. Create a workspace either from a devfile or a sample.
4. Open Developer tools->Network, and make sure there are no requests with 409 Conflict status.
5. Open the Dashboard workspaces list page and make sure there is only one new workspace.

@akurinnoy please, backport to 7.72.x for 3.8 once merged in main

@akurinnoy I tested it. I clicked on a sample and
I see 3 requests {che-server}/dashboard/api/server-config instead of one while creating a new workspace.

Could you fix it too?

Could you fix it too?

@olexii4 I believe that's another issue not related to this one.

[akurinnoy]

@olexii4 FYI the fixup I added (4e56d2a) decreases the number of re-renderings of WorkspaceProgress component.
