Hi Bryan,
The behavior you're seeing is actually by design. The idea of the build breaker widget was to always show who the last person to break the build was, even if the build is not broken anymore. That person's picture will be displayed until the next person breaks the build.
That being said, I understand what you're saying and why you would like to see the build breaker widget show that the build is not broken. Our teams internally like the way it currently functions, but I'm sure there's many people out there who would like it to work the way you describe. I have added a work item to our backlog and we will look into adding this to a future version.
Regards,
Joel
