When adding/filtering by cluster-id in the Hybrid Console page: https://console.redhat.com/openshift, the input field does not trim automatically the white spaces, causing the user to manually inspect and clean the white space. Otherwise it will result in a "Cluster not found" error.

Quick reproducer is, copy and paste a known cluster-id and add manually spaces to the end or in the start of it.
