It's misleading for the twirling loading icon to keep displaying when an error or other message is displayed, as it indicates that the page is still loading when it isn't.

• E.g. The message may say the page has nothing to show for example, so the twirling icon should disappear.

E.g. when an error occurs 'No permission to see this!' the twirling logo keeps displaying. When the error displays the twirling icon should stop, so people don't think something is still loading.
