I think class tooltip with data-content should be prefered over title.

As far as I can see:
The only thing speaking against title is its release date:
It seems to have been accepted into the standard not too long ago, resulting in only being usable on about 55% of all devices.
For the future (say perhaps in three years), I think we should abandon using tooltip with data-content for using title instead as it makes more sense to use the browser-native version than one depending on external JS.

Would approve, but I can't.

title attribute is not a new browser features, it' ancient. It can not be styled and at least in Firefox, it results in a tiny text, with like 10px font size which is borderline unreadable to me, that's why I advocate JS-based tooltips. While there are also CSS-based tooltips, those have far too many issues with z-index and such and I would not consider them.

Ancient?
Why do both Firefox and Chrome only support it since late April 2022 then?
The only browsers it is ancient for are IE and Edge...

That, however, is a valid reason, even though I think this is one of the things, we actually don't want to style ourselves...
The browsers should know themselves what a good default value for it is.

Seems like inaccurate CanIUse data, the MDN table is better:

title attribute dates back to Netscape days I think, it's really ancient. Example reference from 1998:

Better than before, but I'd still prefer all title usage to be refactored to use tooltip later. It's just better UX than title.

OK done.
