Alerts no longer have a button for viewing resource details

Up until a few weeks ago, an Alert which was generated due to a particular resource, for example a PubSub Subscription, would show a button on the alert page which allowed a user to navigate directly from the alert to the particular resource having the issue. At some point this seems to have disappeared and I do not know why. Was this an intentional change? Is there a configuration I need to update to bring the button back?
