The Application filter at the top of the Topology page in the Developer's perspective (only) gets reset back to 'All Applications' after you've selected a specific application group.  Sometimes it doesn't reset.

I could not reproduce in a 4.19.7 ROSA cluster, but it is reproducible in 4.19.10.

    4.19.10

    Testing topology contributions and discovered this bug. Use a 4.19.10 cluster and follow the steps to reproduce below.

    1. Login to a 4.19.10 cluster using admin
    2. Enable the Developer's perspective. You can select 'Enable'
    3. Go to the Developer's perspective and select the Topology tab
    4. Select the project 'openshift-monitoring'
    5. Under the Application filter, change it from 'All applications' to 'openshift-monitoring'.
--> It will reset unexpectedly back to 'All applications'

Note, from what I saw, this only happens in the Developer's perspective
    

Filter resets to 'All applications'    

Filter should remain at 'openshift-monitoring'
