 * Previously, the authentication process for the `/metrics` endpoint was missing a token review check and caused unauthorized requests. As a result, the {product-title} console was prone to `TargetDown` alerts. With this release, the token review for unauthorized requests occurs with the user token provided in the request context. As a result, unauthorized requests to the {product-title} console do not cause `TargetDown` alerts. (link:https://issues.redhat.com/browse/OCPBUGS-57180[OCPBUGS-57180])

As a consequence, the `VirtualizedTable` component malfunctioned because of a missing sort function, and the table sorting functionality was affected on the `PipelineRun` list pages.
