Is it really necessary to have a tooltip to say that if you click on something that is obviously a link then the link will open

As stated elsewhere, this is just to normalise.

Normalise with what. I just had a quick look and I didn't see any instances
of the title field having a tooltip in any manager

Just hover any link to edit an article. The Title exists there and therefore a tip shows, why not for categories?

I agree with adding the title attribute which is the correct and accessible way. I don't agree with showing tooltips.

Yes, obviously, we should have a Title attribute, that's why I added one in this PR.
Concerning the tip: we have a sort of tip by default if we do not add the class, it is the black text on yellow background (Firefox).

Is'nt it better to also normalize this and show it as white on black, as for other tips?

I don't think so. What you are seeing is rendered by the browser and does not require any javascript event to be triggered. Perfect for me.

The patch is working fine, but I think this feature does not have really a advantage, due to the categorie above is hidden from the tooltip.

Before applying the patch no tooltip. After applying the patch the tooltip (edit) pops-up on hover.

RTC based on testing. The maintainer should take the decision on this Closing or Merging. Thanks
