When a user pushes the "publish" button to save their edit, the transmission of the data might not be immediate and thus the bridge would remain open until the data would be sent.
In order to avoid confusion for the user, who would expect an immediate closing of the modal and a visible change of information in the infobox, we should have a loading indicator so they know that their request is being processed.
