Steps to reproduce:

1) Create a ROSA cluster using the CLI in interactive mode
2) Ensure the flags for --default-ingress-excluded-namespaces stage --default-ingress-route-selector baz=quux --default-ingress-namespace-ownership-policy inter-namespace --default-ingress-wildcard-policy WildcardsDisallowed are provided during the cluster creation.
3) Once the cluster is created and in Ready state, edit the application ingress using the command below
lamarach@lamarach-mac ~ % rosa edit ingress --route-selector 'test123=' --cluster=nonsts24 h6w0
I: Updated ingress 'h6w0' on cluster 'nonsts24'

4) Refresh the Networking tab in the UI and observe the results

Expected Result

The CLI should show an error such as "Expected key=value format for label-match" and the edit should not succeed

Actual Result

The CLI does not show any error and this value gets updated in the UI.
When the user clicks on the Edit application ingress button and makes changes to other fields, the Save button is disabled.
