Looking at e.g. mediawiki.org where Flow is also installed the Alerts tab gets accompanied by a Message tab where one of the two is always clickable. (see attachment)

Still it would be much clearer if the active tab had its lable in black text rather than looking like a link. This would also solve the confusion on all wikis that have Echo but not Flow installed.

As seen in my screenshot, this is on MediaWiki.org. Unless this changed, afaik there is nothing in Echo or Flow that ensures "Message" is rendered. It is rendered when there is content only. Which isn't always the case.

There are 2 related issues here:

Context: The "Message" group/tab is only rendered if a user has interacted with a Flow Board (on a particular wiki) in some way. So the vast majority of users (99.9%) will only see "Alerts".

For the original bug-report, we really just need to change the word "Alerts" to black text, so that it doesn't look like a link.

For users who have interacted with Flow, we need to change the active tab's title to black text, and leave the inactive tab as a blue link.

(I'm not sure if that needs to be split into a separate task. Hopefully both issues are simple enough to solve in one go.)
