Currently, only if the commit name is empty, the saving will show that it is wrong. But if there is any text in the commit form, it will go to the server, closing the dropdown without any notification.
However, server can reject the commit with several reasons, either because the note is the same or the versioning is not supported, replying with generic error message.
If commit is saved, it doesn't reply with anything, but the new revision list.
