Cloudformation rollback alarm trigger cannot be removed

Question

I have created Cloudformation stack with rollback trigger alarm configured. Now, I am not able to remove the alarm from the rollback configuration.

To replicate:
1. Have stack with rollback alarm
2. Update stack so that there is no rollback alarm, by providing empty list for "rollback triggers". 
```
"RollbackConfiguration": {
    "MonitoringTimeInMinutes": 2,
    "RollbackTriggers": []
}
```
  Update succeeds, however, the console still shows that rollback trigger alarm is configured.

3. Subsequent updates still check the alarm. I.e on subsequent updates, if an alarm occurs the stack is rolled back.

According to [docs here](https://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_RollbackConfiguration.html): To remove all currently specified triggers, specify an empty list for this parameter.

However, specifying an empty list does not seem to work and I have NO way to remove rollback alarm.

Can anybody replicate?
