Checklist:

• I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

Describe the bug

From the UI, inside an ArgoCD Application, when searching for an application, and if another application with the same name exists in another namespace, duplicated results are returned.

For instance, I have an ArgoCD application called app-1 in namespace namespace-1 and in namespace namespace-2, the results appearing in the search box will be:

• app-1 (current)
• app-1 (current)

This behavior does not happen when searching from the homepage (cad https://[argocd-url]/applications. Instead applications are prefixed by namespace name cad

• namespace-1/app-1
• namespace-2/app-1

To Reproduce

• Create namespace namespace-1 and namespace-2
• Enabled ArgoCD to check Application in namespace namespace-1 and namespace-2
• Create an application called app-1 in namespace-1 and namespace-2
• Login to ArgoCD
• Click on any application For instance namespace/app-1
• Search for app-1 in the search box

Expected behavior

I guess there is two possible behaviors expected

1. Only the application inside the same namespace of the application the user is currently located is returned
2. all application are returned but prefixed by namespace

Personally, I would prefer the second option
