I have whys not whats. Why we waited so much(years!) for such api as a browser built in? Why I feel it overwhelming/not well thought off for such simple use case? I still feel like including a 3rd party library and instantiating a tooltip to be more straight forward, if anything these libraries are built upon years of know how and we don't need to wait for a browser vendor to add a new attribute on his own for a marginal improvement. Marginal improvement one would understand immediately right? No "hint" is a not a simple tooltip. And why the heck we would ever need a table grid to explain a feature that should be simple? I'm so sick of the web platform and its inefficiencies
