HealthChecks UI timeline is not showing for the group when a check starts as Unhealthy

What happened: HealthChecks UI timeline is not showing for the group when a check starts as Unhealthy

What you expected to happen: The timeline should always be displayed if there are some changed statuses (healthy to unhealthy for ex).

How to reproduce it (as minimally and precisely as possible):

.AddCheck(name: "Always Unhealthy", () => HealthCheckResult.Unhealthy())
.AddCheck(name: "Random",
   () =>
   {
      int rndValue = rnd.Next(0, 10);
      return rndValue % 2 == 0 ? HealthCheckResult.Healthy() : HealthCheckResult.Unhealthy();
   });

If you change the first check to Healthy or Degraded, then we have a timeline on the Random check.

The timeline is still displayed for the other microservices.
