Chromium was working on development as recently as September 2021 but reached a point where it was dropped in favor of a popover attribute instead. That seems to make the most sense given that any element can be a popover - we merely need to attach it to the attribute to enable it.
Most times something disappears and I assume I did something wrong. But cracking open DevTools shows this is exactly what's supposed to happen.
Now we have a popover "targeted " to a <button>. When the button is clicked, the popover element toggles visibility. This is where stuff gets really fun because now that CSS is capable of handling logic to toggle visibility, we can focus more on what happens when the click happens.
