"Open" badge on issue does not change to "Closed" when issue is closed by commit without reloading page

Super minor issue, but still an issue ;)

When you close an issue with an commit, on the issue page a commend automatically appears saying the issue has been closed by commit x, but its status is still set to "Open". Screenshot of when this happend on my local gitlab instance:

I am on version 8.6.0 which is not the latest i think, but I cant upgrade now due to reasons, so cannot test if this happens on newer versions. (maybe tomorrow)
